MatroZZZ [7]

Answer:

C

Step-by-step explanation:

7x + 3y = 30 (equation 1)

-2x + 3y = 3 (equation 2)

9x = 27 (subtract the two equations to eliminate y)

x = 3 (divide by 9)

7 * 3 + 3y = 30 (Substitute x = 3 into equation 1, it doesn't matter which equation you substitute into)

21 + 3y = 30 (7 * 3 = 21)

3y = 9 (Subtract 21)

y = 3 (divide by 3)

Answer is (3, 3)

Monthly payments = $195

For one year, paying $195 per month will give a total of : $195 * 12 =$2340

Adding the down payment to get total amount paid = $2340 + $195 = $2535

The interest paid will be : $2535 -$2445 = $90
