Question

Mr. Ross is purchasing a table and chairs for

$1350, including tax and interest. He will pay for
the furniture with monthly payments of $75. If Mr.
Ross has made m payments, which equation best
describes r , the amount of the remaining balance?
A r = (1350 − 75) m
B r = 75m + 1350
C r = 1350 − 75m
D r = 75m − 1350

Answer 1

B. r = 75m + 1350 I think is the answer. I hope this helped you!

Answer 2

Total cost = $1350

m payments of $75 was made. Hence total = m*75 = $ 75m

Remainder = Total - Amount paid

= 1350 - 75m

r = 1350 - 75m

Option C.

I hope this explains it.
