if you take out an $8000 car loan that calls for 48 monthly payments starting after 1 month at an APR of 10%, what is the monthly payment? what is the effective annual interest rate on the loan ?

i know the monthly rate is .83%

also i know the equations I am just confused on how they got the final answer?

for payment they have 202 and i get 5383 using this

payment= 8000/1.486= ?

and effective annual rate = (1 + monthly rate) ^12 -1
