Answer:
Man has to pay $1921.19 per month.
Step-by-step explanation:
The formula of Compound Interest is:
where A = Amount
P = Principle
r = rate
n = Number of Compounding per year
t = total number of year
Here, A = 33,000, r = 9% = 0.09, n = 12(monthly), and t = 48(48 months).
Putting all these values in above formula:
⇒
⇒
⇒
⇒ P = 33000 ÷ 1.4314 = 23054.35
Monthly payment = 23054.35 ÷ 12 = 1921.19
Hence, Man has to pay $1921.19 per month.
