A.) 13. all you have to do is plug it into google
The equation for interest is
'Initial amount (interest rate in decimal form) ^ times compounded EX: years'
your equation would be

which equals 592.097713 (not rounded)
This will be a little complex number...
assume 35 years ago, it cost x dollars
for now: x×
=25.25
solve it! :) maybe too difficult without a calculator
