If joe has $5,600 today and invests it for 12 years at a 10 percent interest rate, how much will he have in 12 years?

I assume the current practice of compound interest rates.  But since the compounding period is not specified, I assume it to be annual.

If the above assumptions are correct, then
Future value = present value *(1+r)^n
=5600(1+0.1)^12
=$17575.20

If the assumptions are incorrect, please comment.

Ithink you're supposed to multiply 12.50 which is how much he makes per hour and then multiply it by each number then add whats left togrther and there's your answer
