Calculate the amount for each section using compound interest.?

Compound interest formula

A=P(1+(r/n))^(t*n)

A = amount at end

P = Principal

r = annual interest rate (convert to decimal for formula)

t = # of years

n = # of times compounded per year

^ is the sign for exponent

Thank you!

1000(1+0.03/2)2*8

A) $1000 invested at 3%/a compounded semiannually for 8 years

B) $5500 invested at 6%/a compounded monthly for 42 months

C) $1000 borrowed at 5%/a compounded quarterly for 5.5 years

How do we find the answer
