I need help with the second one not the first one.

Use the compound interest formula to find the future value A for the following values. P= $1,500 i = 0.079 n=20 A=$ (Round to the nearest cent.) Find i (the rate per period) and n (the number of periods) for the loan at the given annual rate. Quarterly Payments of $3000 are made for 4 years to repay a loan at 10.2% compounded quarterly. Round the rate per period to six decimal places. O A. i=0.102000; n = 16 O B. i=0.006375; n=4 OC. i=0.025500, n=4 OD. i=0,025500; n = 16
