Jerry’s new car has a list price of $22,415. the sales tax in jerry’s state is 8.75%, and he is responsible for a $1,925 vehicle licensing fee and a $79 documentation fee. jerry plans to make a down payment of $3,000 and finance the rest at an interest rate of 10.86%, compounded monthly. if jerry’s financing plan spans three years, what will his monthly payment be?

Given:
list price = 22,415
sales tax = 8.75%
vehicle license fee = 1,925
documentation fee = 79
down payment = 3,000
finance the rest at 10.86% compounded monthly for 3 years.

22,415 x 1.0875 = 24,376.31
24,376.31 + 1,925 + 79 = 26,380.31
26,380.31 - 3,000 = 23,380.31

I used an auto loan calculator and inputted the required info. 
It gave the answer of 763.88 monthly payment.

When you do manual calculation, you use this formula.

A = P * {[r(1+r)^n] / [(1+r)^n - 1]}

A = monthly payment
P = pricipal
r = interest rate per month
n = total number of months
