Jeffery wei received a 6 year non subsidized student loan of 30000 at an annual interest rate of 5.2%. what are jeffery’s monthly loan payments for this loan after he graduates in 4 years

If the loan interest rate remains at i=5.2%/12 per month throughout the six years, 
then amount owing after 4 years, or the future value 


    to the nearest cent

Monthly payment, A, required to repay the loan in two years (24 months)


  to the nearest cent.

Jeffrey will have to repay $1623.03 monthly during the last two years of his loan to owe nothing at the end of the 6 years loan period.

Ithink the answer is last one.
