Katelyn plans to apply for a $10,000 loan at an interest rate of 5.6% for 5 years. Use the monthly payment formula to complete t

SashulF [63]

Answer:

Katelyn's monthly payment for the loan is $ 2,032.52

Step-by-step explanation:

The formula given is explicit,we can solve for monthly payment using the below formula

P=L(1-r/r-r^n+1)

r=1/(1+i)

i=5.6%/12=0.47%

5.6% is an annual interest rate,it would be appropriate to restate in monthly terms

r=1/(1+0.47%)=0.995

n=5 years*12 months=60

L is the loan amount of $100,000

P=100000*(1-0.995)/(0.995-0.995^60+1)

=100000*(1-0.995)/(0.995-0.74)

=100000*0.005/0.246

=$ 2,032.52

1. Solve the system by using a table. 3y=4x+7 , -4x-4y=28. These are the possible solutions: A) (–4, –3), B) (–3, –4), C) (4, 3)

<span>The first question:
3y=4x+7 (1)
-4x-4y=28 (2)

Let's plug in x = -4, -3, 3, and 4 and see the y-values :)

I have attached the table since it's hard to make a table with text :P
As you can see, when x = -4, that is when the y-values are equal. That means that is the solution to the system of equations. Your answer is A) (-4, -3).

The second question:
</span><span>-3x-y=-10 (1)
4x-4y=8 (2)
</span>
When you graph both equations, you will see that they intersect at D) (3, 1).

The third question:
We need to find the lines for revenues and expenses.
To find the line for revenues, make months the x-value and revenues the y-values. And find the equation. You should get y = 4,100x + 300.
To find the line for expenses, make months the x-value and expenses the y-values. And find the equation. You should get y = 1,900x + 19,990.

Now graph both solutions and see where they intersect. They intersect at approximately (8.95, 36995)

That would be during the month of C) August.
