Question

Cameron bought a used car for $4,500. He made a down payment of $1,200 and agreed to pay the remaining balance in monthly payments of $300 each.

Which equation can be used to find m, the number of months it will take Cameron to pay off his car? (7.10A)


F 4,500 = 1,200 + 300m
F 4,500 = 1,200 + 300m

G 4,500 = –300 + 1,200m
G 4,500 = –300 + 1,200m

H 4,500 = 300 + 1,200m
H 4,500 = 300 + 1,200m

J 4,500 = 1,200 – 300m
J 4,500 = 1,200 – 300m

Answer 1

`4500 = 1200 + 300m`

Explanation:

Given

`Total = 4500`

`Base\ Amount = 1200`

`Payment = 300` monthly

Required

Write an expression to determine the number of months

The total can be expressed using:

`Total = Base\ Amount +Payment * Number\ of\ months`

Substitute value for each term

`4500 = 1200 + 300 * m`

`4500 = 1200 + 300m`

Hence:

Option F answers the question
