Step-by-step explanation:

We are given

Adan has decided to purchase an $9000 car

he plans on putting 20% down toward the purchase

so,

loan amount =  80% of 9000

financing the rest at 7.9% interest rate for 3 years

so,

r=7.9%=0.079

now, we can find i

i=0.00658

t=3

we can use formula

now, we can plug values

now, we can simplify it

So,

His monthly payment is $225.2765
