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

                                         Person A    Person B

Total investment = 3years of lost wages plus college cost
                             = 3*18000 + 45000

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
