He must pay a 10% down-payment and the rest at a $116 monthly payment for 18 months.

<u>B. What is the total amount of the monthly payments</u>
A monthly payment of $116 for 18 months, i.e

It is the sum of down-payment and total monthly payments, i.e
<u>D. What is the total finance charge</u>

<u> E. If Jean models her payment plan as an arithmetic sequence, give the first term a1 and the common ratio d</u>
As he paid the down-payment of $198 and then a constant monthly payment of $116, so
The first term = 198
common difference = 116
The A.P. series will be, 198, 314, 430, 546, 662,.................., 2286
