Marcus' employee benefits include family health care coverage. He contributes 25% of the cost. Marcus gets paid weekly and $102 is taken out of each paycheck for family healthcare coverage. How much does his employer contribute annually for coverage?
Monthly amount, M = $102×4 = $408.
Also, yearly amount, Y = M×12 = $408×12 = $4896
It is given that 25% of the cost is contributed by Marcus.
Amount Marcus paid
[tex]=\dfrac{\$4896 \times 25 }{100}\\\\= \$1224[/tex]
Therefore, his employer contribution annually for coverage is $( 4896 - 1224)=$3672.
Hence, this is the required solution.

3y=6x+3 and 3y=4x+6
Answer:
x=3/2, y=4Step-by-step explanation:
3y=6x+3
solve by substitution for 3y=6x+3
3y=4x+6
6x+3=4x+6
6x-4x=6-3
2x=3
x=3/23y=6x+3 ⇒ y=6x/3 + 3/3 ⇒ y=2x+1

2) Albert has a $16,000, six-year loan with an APR of 7.25%.
a. What is the monthly payment?
b. What is the total amount of the monthly payments?
c. What is the finance charge?
For a standard, year $16000 home/car loan 7.25% APR with payments due at the end of the month, calculate the monthly payment:
Calculate Months:
Your loan term is for years.
Months = 12 * Years
Months = 12 *
Months = 0
Now calculate monthly Annual Percentage Rate (APR):
APR = Annual APR
12
APR = 7.25
12
APR = 0.0060416666666667 <----- This is the effective interest each month.
Now calculate Annual Percentage Yield (APY):
APY = ((1+APR)12 - 1) * 100%
APY = ((1 + 0.0060416666666667)12 - 1) * 100%
APY = ((1.0060416666667)12 - 1) * 100%
APY = (1.0749582974213 - 1) * 100%
APY = 0.074958297421329 * 100%
APY = 7.5% <----- What you actually pay in interest with monthly compounding.
Calculate our monthly loan payment:
Monthly Payment = Loan Amt * APR
1 - (1/(1 + APR))n
Monthly Payment = 16000 * 0.0060416666666667
(1 - (1 /(1 + 0.0060416666666667))0
Monthly Payment = 96.666666666667
(1 - (1 / 1.0060416666667)0
Monthly Payment = 96.666666666667
1 - 0.99399461586250
Monthly Payment = 96.666666666667
1 - 1
Monthly Payment = 96.666666666667
0
Monthly Payment = 0
Now calculate the total number of payments you will make:
Total Payments = Monthly Payment * Months in the Loan
Total Payments = 0 * 0
Total Payments = $0.00
You will end up paying $0.00 - $16,000.00 = $-16,000.00 above the principal on this loan.

Answer:
C) 3^3*x^-3
Step-by-step explanation:
okay, so let's just find the numerator and denominator separately
So 27 is equal to 3^3. Numerator done.
Now for the denominator:
You need to know the laws of indices, specifically the one which says that square root of something is the same as to the power of 1/2, where the 1 signifies the power of the number inside the root and the 2 is for the square root. This means that the cube root would be power of 1/3.
So here cube root of x^9, would be equivalent to x^9/3, which can be simplified to x^3/1 ---> x^3.
This leaves us with 3^3/x^3. However, this isn't an option. We need to simplify the divide part of the expression. We can do that by using another law of indices which states that anything to the power of a negative number is the same as 1 over that number. (For example, x^-5 = 1/x^5) If there are numbers in front of the x, then that number would replace the 1, such as the following example: 9x^-3 = 9/x^3.
In this question, our 3^3/x^3 could be changed using this law to give, 3^3*x^-3

The sum of the two numbers is 52 and the difference is 28. Calculate the numbers.
Let's set these two numbers as 'a' and 'b'
Now, let's set up equations based on the information known:
the sum of the two numbers is 52 --> a + b = 52the difference is 28 --> a - b =28Equations
a + b = 52 -- equation 1a - b = 28 -- equation 2Solve:
(Equation 1) + (Equation 2)
2a = 80
a = 40 -- equation 3
(Equation 3)
40 + b = 52
b = 12
So a = 40 and b = 12

A six-sided die is rolled 2 times. What is the fractional probability of rolling different numbers?
Answer:
The probability of getting 6 the first time and an even number the second time is 1/12.
what is probability?
probability is the quantification of possibilities in numbers.
(1) probability of rolling a 6 for the first time:
total possible outcomes = (1,2,3,4,5,6) =6
sample space = 1
probability of getting 6 = sample space/total possible outcomes
probability of getting 6 = 1/6
2)probability of getting an even number
total possible outcomes will be (1,2,3,4,5,6)
sample space = (2,4,6) ie 3
probability of this = 3/6 = 0.5
total probability = 1/6*0.5 = 1/12
therefore,
The probability of getting 6 the first time and an even number the second time is 1/12.

The bill for the repair of a car was $357. The cost for the parts was $285. The cost of labor was $32 per hour. Use an equation to find out how long it took for the mechanic to repair the car?
Answer:
2.25 hours
Step-by-step explanation:
Hope this helps! sorry was a tad bit late
It took 2 hours and 15 minutes to repair the car.
How to form an equation?Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.
In other words, an equation is a set of variables that are constrained through a situation or case.
Given that,
Total bill for the repair of car = $357
Let's say it took x hour to repair the car
So,
32x will be the labor cost
Now,
Labor cost + cost of parts = total bill
So,
32x + 285 = 357
32x = 72 ⇒ x = 2.25 hour
Now,
0.25 hour in minutes ⇒ 0.25 × 60 = 15 minutes.
Hence "It took 2 hours and 15 minutes to repair the car".

[tex]\frac{2}{3} +\frac{1}{3} = 1[/tex]
[tex]\frac{1}{2} - \frac{1}{6} = \frac{3-1}{6} = \frac{1}{3}[/tex]
Answer:
1/12 + 16 = 1/4
1/4 - 1/8 = 1/8
2/3 + 1/3 = 1
1/2 - 1/6 = 1/3
Step-by-step explanation:
1/12 + 1/6
LCM of denominators 12 and 6 = 12
1/6
Multiply 2 to both numerator and denominator,
1/6 * 2/2
= ( 1*2 )/( 6*2 )
= 2/12
1/12 + 1/6
= 1/12 + 2/12
= ( 1 + 2 )/12
= 3/12
12 = 3*4
3/12
= 3/( 3*4 )
= 1/4
1/4 - 1/8
LCM of denominators 4 and 8 = 8
1/4
Multiply 2 to both numerator and denominator,
1/4 * 2/2
= ( 1*2 )/( 4*2 )
= 2/8
1/4 - 1/8
= 2/8 - 1/8
= ( 2 - 1 )/8
= 1/8
2/3 + 1/3
= ( 2 + 1 )/3
= 3/3
= 1
1/2 - 1/6
LCM of denominators 2 and 6 = 6
1/2
Multiply 3 to both numerator and denominator,
1/2 * 3/3
= ( 1*3 )/( 2*3 )
= 3/6
1/2 - 1/6
= 3/6 - 1/6
= ( 3 - 1 )/6
= 2/6
6 = 2*3
2/6
= 2/( 2*3 )
= 1/3

Does the point (-1, 2) make the following equations true? i) y = -2x ii) y = x + 3
Answer:
i) True
ii) True
Step-by-step explanation:
Given :-
Point (-1, 2)
To Find :
Whether the point is a solution of :
y = -2xy = x + 3Solving :-
Substitute the value of the point in each of the equations.
=> y = -2x
=> 2 = -2(-1)
=> 2 = 2 [∴ The point makes it true]
=> y = x + 3
=> 2 = -1 + 3
=> 2 = 2 [∴ The point makes it true]
Answer:
true
Step-by-step explanation:
first, you take the y = -2x and plug that into y = x + 3. so your equation should be -2x = x + 3. you then solve for x which comes out to be -1. you then plug the -1 into y = -2x. your equation should be y = -2(-1). solve for y which equals 2. the point that you got from both equations matches the point from the equation given so it is true.

Answer:
x = 3
Step-by-step explanation:
x + 9 = 12
To solve the equation, we have to isolate 'x'.
To isolate x, subtract 9 from both sides.
x + 9 - 9 = 12 - 9
x = 3
Answer:
[tex]\boxed{\sf{x=3}}[/tex]
Step-by-step explanation:
The only thing you need to do to solve this problem is to isolate the term x from one side of the equation.
x+9=12
First, subtract by 9 from both sides.
[tex]\sf{x+9-9=12-9}[/tex]
Solve.
[tex]\sf{12-9=3}[/tex]
