Answer:
last installment is $540
Step-by-step explanation:
principal amount (p) = $7500
rate (r) = 16.5 %
installment = $300
to find out
full payment is increased to pay off the loan and the last smaller payment is made one month after the last full payment
solution
we know monthly installment is $300 so amount will be paid i.e.
amount = $300×12×N ..............1
here N is no of installment
and we know amount formula i.e.
amount = principal ( 1+r/100)^N
put amount value and principal rate
300×12×N = 7500 ( 1+16.5/100)^N
(3600 ×N ) / 7500 = 1.165^N
0.48N = 1.165^N
by the graphical we will get N = 3.65
so 3.65 year
so as that put N in equation 1 we get
amount = $300×12× 3.65
amount = $13140
we can say there are 43 installment so remaining money is $13140 - ($300 × 43 installment )
i.e. = $240 and last installment will be $300 + $240 = $540
so last installment is $540
