The new mean annual wage is; $ 43,149.82.
Given that the initial mean weekly wage is $ 2.117.
The growth rate is 4.75%.
We need to find a new annual wage.
Consider the equation, A be the new annual wage.
Here R is the growth rate and P is the initial mean weekly wage and T is the number of weeks in a year.
The number of weeks in a year = 52 weeks.
Substitute P= 2,117, R =4.75% = 0.0475and T =52 in the equation.
A = 2.117 x 52(1 + 0.0475)
A = 43,149.82

a. Determine whether the model represents
exponential growth or exponential decay.
b. Identify the annual percent increase or decrease
in the value of the bike.
c. Estimate when the value of the bike will be $50.
C
The model y = 200(0.65)ⁿ represents exponential decay because the value of the bike decreases over time as t increases.
The value of the bike decreases by approximately 40.67% per year.
The value of the bike will be $50 approximately 5.2 years after it was purchased.
How to calculate the valuesa. A = Peⁿ = 200e⁻⁰.⁴³⁰⁷≈ 118.66
The value of the bike after one year is approximately $118.66.
b. percent decrease = (initial amount - final amount) / initial amount * 100%
percent decrease = (200 - 118.66) / 200 * 100% ≈ 40.67%
c. We can set y = 50 in the model and solve for t:
50 = 200(0.65)ⁿ
0.65ⁿ = 0.25
Taking the natural logarithm of both sides, we get:
ln(0.65ⁿ) = ln(0.25)
t ln(0.65) = ln(0.25)

Garden County provides the following information in order to prepare reconciliations between governmental fund financial statements and government-wide financial statements (fiscal year 1/1/2022 to 12/31/2022).
Total Fund Balance 12/31/22 $200,000
Total Change in Fund Balance for the year ending 12/31/22 $50,000
Capital Assets: 1) Acquisition value of 1/1/22 capital assets of $10,000,000 with an associated accumulated depreciation $5,200,000; 2) During 2022 Garden County purchased new capital assets equal to $1,000,000; 3) During 2022 Garden County sold capital assets with a book value of $30,000 for $32,000 cash; 4) 2022 Depreciation expense is equal to $500,000.
Bonds Payable: 1) Bonds Payable outstanding as of 1/1/22 is $3,200,000; 2) An additional issuance at face value during 2022 equals $400,000; 3) A repayment of bonds payable of $200,000 occurred during 2022.
Interest on LT Debt: 1) Accrued interest payable exists as of 12/31/2022 but was not accrued in the governmental fund (not due and payable) in the amount of $180,000.
Property taxes: All property taxes receivable were collected in 2022 with the exception of $80,000. Of that $80,000, $60,000 is expected to be collected within the first 60 days of 2023 and the remainder beyond that time period.
Part A: Prepare a reconciliation between the Governmental Fund Balance Sheet and the Government-wide Statement of Net Position at 12/31/22. Use proper headings and show any supporting computations for full credit.
Part B: Prepare a reconciliation between the Governmental Fund Statement of Revenues, Expenditures, and Changes in Fund Balance and the Government-wide Statement of Activities for the year ending 12/31/22. Use proper headings and show any supporting computations
Answer:
governmental fund financial statements and government-wide financial statements have different purposes and accounting methods. Governmental fund financial statements focus on the short-term financial performance and accountability of individual funds, using the modified accrual basis of accounting. Government-wide financial statements provide a broader and longer-term perspective of the government's financial position and activities, using the full accrual basis of accounting.
To reconcile between these two types of statements, some adjustments are needed to account for the differences in measurement focus and basis of accounting. Here are the steps to prepare the reconciliations for Part A and Part B:
Part A: Reconciliation between the Governmental Fund Balance Sheet and the Government-wide Statement of Net Position at 12/31/22.
- Start with the total fund balance of the governmental funds as reported in the fund balance sheet ($200,000).
- Add the net value of capital assets (acquisition value minus accumulated depreciation) as reported in the government-wide statement of net position. This is because capital assets are not reported in governmental fund financial statements, but are reported in government-wide financial statements. The net value of capital assets can be calculated as follows:
- Acquisition value of capital assets as of 1/1/22: $10,000,000
- Plus: Purchases of capital assets during 2022: $1,000,000
- Less: Sales of capital assets during 2022: $30,000
- Equals: Acquisition value of capital assets as of 12/31/22: $10,970,000
- Less: Accumulated depreciation as of 1/1/22: $5,200,000
- Less: Depreciation expense for 2022: $500,000
- Equals: Accumulated depreciation as of 12/31/22: $5,700,000
- Net value of capital assets as of 12/31/22: $5,270,000
- Subtract the amount of bonds payable as reported in the government-wide statement of net position. This is because bonds payable are not reported in governmental fund financial statements, but are reported in government-wide financial statements. The amount of bonds payable can be calculated as follows:
- Bonds payable as of 1/1/22: $3,200,000
- Plus: Issuance of bonds payable during 2022: $400,000
- Less: Repayment of bonds payable during 2022: $200,000
- Bonds payable as of 12/31/22: $3,400,000
- Subtract the amount of accrued interest payable on long-term debt as reported in the government-wide statement of net position. This is because accrued interest payable is not reported in governmental fund financial statements, but are reported in government-wide financial statements. The amount of accrued interest payable is given as $180,000.
- Add the amount of property taxes receivable that are not available to pay current liabilities as reported in the governmental fund balance sheet. This is because property taxes receivable that are not available are not recognized as revenues in governmental fund financial statements, but are recognized as revenues in government-wide financial statements. The amount of property taxes receivable that are not available can be calculated as follows:
- Total property taxes receivable as of 12/31/22: $80,000
- Less: Property taxes receivable expected to be collected within 60 days of year-end: $60,000
- Property taxes receivable that are not available as of 12/31/22: $20,000
- The resulting amount is the net position of governmental activities as reported in the government-wide statement of net position.
The reconciliation can be presented in a table format as follows:
| Reconciliation of Total Fund Balance to Net Position | Amount |
| ----------------------------------------------------- | ------ |
| Total fund balance - governmental funds | \$200,000 |
| Capital assets used in governmental activities are not financial resources and therefore are not reported in the funds | \$5,270,000 |
| Long-term liabilities applicable to governmental activities are not due and payable in the current period and therefore are not reported in the funds | \(-\$3,580,000\) |
| Revenues in the statement of activities that do not provide current financial resources are not reported as revenues in the funds | \$20,000 |
| Net position - governmental activities

Write the expression using only positive exponents. Assume no denominator equals zero.
(−3^4 ^−7)^−3
Answer: (-3^4^-7)^-3 can be expressed with positive exponents as (-1/3^4^7)^3.
Step-by-step explanation:
First, we need to evaluate the exponents of the expression from the highest power to the lowest power. Since the exponent of 7 is negative, we need to apply the rule that a negative exponent indicates a reciprocal. Therefore, we can rewrite the expression as (-3^4^-1/7)^-3.
Next, we can simplify the expression -1/7 by flipping it to 7^-1. Therefore, we now have (-3^4^7^-1)^-3.
We can now evaluate the exponent of 4, which gives us (-3^16384^-1)^-3.
Finally, we can simplify 16384^-1 by flipping it to 1/16384, which gives us (-1/3^1/16384)^3.
This expression can be written using only positive exponents as (-1/3^4^7)^3.
17. Rob purchased a boat three years ago. The boat decreased by 7% each year. Three years
later, the value of the boat was $32,174.28. Which equation initially models the value of Rob's
boat?
A. y = 40,000(0.93)*
B. y = 40,000(1.07)*
C. y = 32,174.28 (0.93)*
D. y = 32,174.28 (1.07)*
Answer:
The correct equation that initially models the value of Rob's boat is option A, y = 40,000(0.93)*.
Since the value of the boat decreased by 7% each year, the value of the boat after three years can be represented by:
y = 40,000(0.93)^3
where y is the value of the boat after three years, and 40,000 is the initial value of the boat.
Simplifying this equation, we get:
y = 40,000(0.7951)
y = 31,804
However, we know that the actual value of the boat after three years was $32,174.28. This means that our initial assumption that the boat decreased by 7% each year is incorrect and we need to adjust the equation accordingly.
To find the correct equation, we can use the formula for exponential decay:
y = a(1 - r)^t
where y is the final value, a is the initial value, r is the rate of decay (expressed as a decimal), and t is the time in years.
In this case, we know that the final value of the boat is $32,174.28, and that the boat was owned for three years. We also know that the value of the boat decreased by 7% each year.
So we can set up an equation:
32,174.28 = 40,000(0.93)^3
Simplifying this equation, we get:
32,174.28 = 31,804.00
This equation is approximately true, which means that the initial value of the boat was $40,000 and the correct equation that initially models the value of Rob's boat is:
y = 40,000(0.93)^t
where t is the time in years.

Step-by-step explanation:
Plug in the x-coodinate and it should equal your desired y value
Tom took a trip of 1,300 miles. He traveled by train at 50 miles an hour and the same number of hours by plane at 275 mph. How many hours did the trip take?
3 hours
8 hours
4 hours
Tom traveled for 4 hours by train and 4 hours by plane, for a total trip time of 8 hours.
We have,
Let's call the number of hours Tom traveled by train t.
Since he traveled the same number of hours by plane, he also traveled for t hours at 275 mph.
The total distance he traveled is given by the sum of the distances traveled by train and by plane:
Distance by train = 50t
Distance by plane = 275t
Total distance = 1300
So we can set up the equation:
50t + 275t = 1300
Simplifying and solving for t, we get:
325t = 1300
t = 4
Therefore,
Tom traveled for 4 hours by train and 4 hours by plane, for a total trip time of 8 hours.
