Answer:
b. 2.5 years
Step-by-step explanation:
In order to go to school, James would be giving up his job which pays $42,000 per year. For the two years, he would be giving up- $42,000 × 2 = $84,000
The cost of school for the two years = $28,000 x 2 = $56,000
Total investment = $84,000 + $56,000 = $140,000
Time taken to recover investment =
$140,000 / $56,000 = 2.5 years
