Mark currently works part-time with a salary of $8,000 per year. mark plans to quit working and attend college for 4 years. if his college costs will total $64,000, how long will it take mark to recover his investment assuming he has a salary of $32,000 upon graduating?

For the answer to the question above asking how long will it take a mark to recover his investment assuming he has a salary of $32,000 upon graduating?

The answer is Mark will lose:
4 * $ 8,000 = $32,000 ( without salary ) + $64,000 ( college costs ) = 
= $96,000 in total
$96,000 : $32,000 = 3

It will take Mark 3 years to recover his investments. Poor Mark

What’s the improper fraction?
