Dan buys a car for £2500.
It depreciates at a rate of 4.2% per year.
How much will it be worth in 4 years?
Give your answer to the nearest penny where appropriate.
Answer:
£2080.00
Step-by-step explanation:
4.2%*4= 16.8%
16.8%*2500= 420
2500-420= 2080
The value of the car after 4 years of depreciation is approximately £2105.80 to the nearest penny.
What is the depreciation rate?The rate of depreciation is the percentage by which the value of an asset decreases over time.
To calculate the value of the car after 4 years, we need to apply the depreciation rate of 4.2% to the original value of £2500 for each year.
First, we can calculate the value of the car after one year:
Value after one year = £2500 - 4.2% of £2500
= £2500 - 0.042 x £2500
= £2500 - £105
= £2395
Then, we can use this value as the starting point to calculate the value after two years,
Value after two years = £2395 - 4.2% of £2395
= £2395 - 0.042 x £2395
= £2395 - £100.29
= £2294.71
Similarly, we can repeat this process for the third and fourth years:
Value after three years = £2198.26
Value after four years = £2105.80
Therefore, the value of the car after 4 years of depreciation is approximately £2105.80 to the nearest penny.

3(2x - 5) = 9(10 - x)
Answer:
x=7
Step-by-step explanation:
3(2x - 5) = 9(10 - x)
6x-15=90-9x
6x+9x=90+15
15x=105
x=7
Answer:

Which of the following represents the probability that someone who
works full time has more than $5,000 in credit card debt?
(A) P(full time and credit card debt over $5,000)
(B) P(full time or credit card debt over $5,000)
(C) P(full time credit card debt over $5,000)
(D) P(credit card debt over $5,000 | full time)
(E) P(full time)*P(credit card debt over $5,000)
Answer:
The correct option is;
(E) P(full time) × P(credit card debt over $5,000)
Step-by-step explanation:
The given parameters are;
The mode of employment of a person = Full time
The amount of debt in the credit card = More than $5,000
The probability that a person works full time = P(full time)
The probability that the person has over $5,000 in credit card debt = P(credit card debt over $5,000)
Therefore, the probability that someone who works full time has more than $5,000 in credit card debt = P(full time) × P(credit card debt over $5,000)

Answer: See explanation
Step-by-step explanation:
1. What is the 5th term of the arithmetic sequence an= 5n + 1 ?
This will be:
= 5n + 1
= 5(5) + 1
= 25 + 1
= 26
2. What is the next 3 terms of the Fibonacci sequence 0, 1, 1, 2, 3, 5,....
Fibonacci sequence means that you'll add the two previous numbers given to get the next number. Therefore, the next numbers will be:
3+5 = 8
5+8 = 13
8 + 13 = 21
The numbers are 8, 13 and 21.
3. What are the missing numbers in the sequence 4, ---,_,_, 64 ?
a = 4
ar^4 = 64
We replace a with 4
4r^4 = 64
r^4 = 64/4
r^4 = 16
r = 2
2nd term = ar = 4 × 2 = 8
3rd term = ar^2 = 4 × 2^2 = 4 × 4 = 16
4th term = ar^3 = 4 × 2^3 = 4 ×✓8 = 32
The numbers are 8, 16 and 32.
4. What is the common ratio of the given sequence 3, -6, 12,-24, 48 ?
Common ratio = 2nd term / 1st term
= ar / a
= -6/3
= -2
5. What is the 10th term of the arithmetic sequence an = 3n - 5 ?
an = 3n - 5
= 3(10) - 5
= 30 - 5
= 25
6. If a1 = 2, d = -2, then what is a 12?
a12 = a + (n - 1)d
a12 = a + (12 - 1)d
a12 = a + 11d
a12 = 2 + 11(-2)
a12 = 2 - 22
a12 = -20
7. What is the common ratio of the given sequence 1000, 500, 250, 125?
Common ratio = 2nd term / 1st term
= 500 / 1000
= 1/2
8. What is the 8th term of the sequence -10, - 8, -6, -4, ...?
a = -10
d = -8 - (-10) = -8 + 10 = 2
8th term = a + (n - 1)d
= a + (8 - 1)d
= a + 7d
= -10 + 7(2)
= -10 + 14
= 4

At Fenway park, they sell 5000 hot dogs at $4 per dog. They also know that for each quarter (25 cents) they raise the price, they will sell 200 less dogs. How many hot dogs should they sell to maximize profit?
Answer:
4,100
Step-by-step explanation:
Let x be increase in the price % and f(x) be revenue
Revenue = Sales price*Total number hot dog sold
Hot dog sold = $4/dog
Now when increase in $0.25. Then, Revenue f(x) = (4+0.25x) (500 - 200x)
f(x) = 2000 - 800x + 1250x - 50x^2
f(x) = -50x^2 + 450x + 2000
To maximize revenue, we have to find f1(x) and find the value of x for which f1(x) = 0
f1(x) = -100x + 450
0 = 0100x + 450
x = 4.5
Hence, to maximize profit number of hot dog they sell: 5000 - 200(4.5)
= 5000 - 900
= 4100
Thus, the number of hot dog sold = 4,100
Write the equation of a line that is perpendicular to the graph of y = 1/2 x + 3, and passing through the point (-3, 5). Show work
Answer:
Perpendicular lines have opposite-reciprocal slopes, so the slope of the line we want to find is 1/2. Plugging in the point given into the equation y = 1/2x + b and solving for b, we get b = 6. Thus, the equation of the line is y = ½x + 6.

A slope of −3, passing through the point (15,−50).
Show your work in the sketch box on the left.
Step 1: Substitute values for m, x, and y.
Step 2: Solve equation for b.
Step 3: Rewrite your equation with only m and b.
What is the equation of this line?
Answer:
Y = -3x + 90
Step-by-step explanation:
Y= Mx + b
M - (-3)
X - 15
Y - (-50)
Y = Mx + b
50 = (-3)(15) + b
50 = -45 + b
95 = b
Y = -3x + 90

The stock of Company A gained 2% today to $79.56. What was the opening price of the stock in the beginning of the day?
Answer: $78
Step-by-step explanation:
From the question, we are informed that the stock of Company A gained 2% today to $79.56. The opening price of the stock in the beginning of the day will be calculated as:
= [100% / (100% + 2%)] × 79.56
= (100% / 102%) × 79.56
= 1/1.02 × 79.56
= 79.56/1.02
= 78
Therefore, opening price of the stock in the beginning of the day is $78

(-10, - 16). Which of the following is the slope
of the line?
Answer:
Option B
Step-by-step explanation:
In order to find the answer you must use the formula for slope, substitute the values, and solve.
[tex]P = (0,2) = (x1,y1)[/tex]
[tex]P=(-10,-16)=(x2,y2)[/tex]
[tex]Slope = \frac{y2-y1}{x2-x1}[/tex]
Substitute:
[tex]Slope = \frac{-16-2}{-10-0}[/tex]
Solve:
[tex]-16-2=-16+-2=-18[/tex]
[tex]-10+0=-10[/tex]
[tex]=\frac{-18}{-10}[/tex]
Reduce:
[tex]18\div2=9[/tex]
[tex]10\div2=5[/tex]
Remember that a negative divided by a positive equals a negative
[tex]=-\frac{9}{5}[/tex]

What is the quantity of pairs and how much are they each pair??
Answer:
They buy at wholesale and sell at an 80% markup. The retail prices are;
0 - 20 pairs.

81 or more pairs
= 17 * 1.80
= $30.60
