The price of the computer is 4 285 dollars which you borrowed for an installment plan.
Let's solve for the APR and the monthly payment.
The interest  charge is 513.26 dollars for 36 months
=> 36 months = 3 years
=> 513.26 / 3 years = 171.1 dollars per year is the interest.

=> 4 285 + 513.26 = 4 798.26 dollars 
=>  4 798.26 dollars  /3 years = 1599.42 dollars per year
=>599.42 dollars / 12 months 133.29 dollars per month
