You need to know the equation for future value of money for this problem. Once you know it, this problem is a piece of cake:

Where:
FV = Future Value
PV = Present Value
r = Annual Interest Rate
n = number of periods.
You have all this information, so just plug it in. (Note 7.5%=0.075)

Wow, $250 grew to almost $740! That's the "miracle" of compound interest. So start saving now!

Note: When you post investment problems you should indicate
if the investment is made at simple interest or at compound interest rules.
-------------------------------
Using Simple interest forms:
A(t) = P(1 + rt)
A(15) = 250(1+0.075*15) = $531.25
-----
Using interest forms with yearly compounding:
A(t) = P(1 + (r/n))^(nt)
A(15) = 250(1+(0.075/1))^15 = $739.72
