Loan , interest rate and APR

You want to buy a car which is worth $7500 but you can only pay $1500, so you need to borrow $6000 from credit A

Credit A APR=15%, Length of loan=3 years, monthly payment=$205.07, Total finance charge=$1382.52 Total cost=$7382.52

Question: how can we calculate the monthly payment is $205.07 because I had a different answer:

6000/36+2000*(0.15/12)=$191.66667

please show me the step for how to get that answer=$205.07
