Create a table to show the given data in tabular form.

                                         Person A    Person B
                                             
Salary prior to school      $18,000     $27,000
Years attending college              3                 4
Total cost of college        $45,000    $30,000
Salary upon graduating   $33,000    $37,000

Person A:
Total investment = 3years of lost wages plus college cost
                             = 3*18000 + 45000
                             = $99,000
Time to recover the investment = 99,000/33,00 = 3 years

Person B:
Total investment = 4* 27000 + 30000
                             = $138,000
Time to recover the investment = 138,000/37,000 = 3.73 years

Therefore it takes person A less time to recover the investment.

a
Person A recovers their investment in a shorter amount of time.
