Final answer:
The benefit-cost ratio of getting a college-required job after five years is 1.93, which means the benefits outweigh the costs.
Step-by-step explanation:
To calculate the benefit-cost ratio of getting a college-required job after five years, we need to consider the present worth of the student loans and the additional wages gained from the job. The present worth of the student loans is $30,000. The additional wages gained from the job are $15,000 per year for five years, which is a total of $75,000. Using an interest rate of 6%, we can calculate the present worth of the additional wages:
Present Worth = Future Value / (1 + Interest Rate)^Number of Periods
Present Worth = $75,000 / (1 + 0.06)^5
Present Worth = $57,977.10
The benefit-cost ratio is calculated by dividing the present worth of the additional wages by the present worth of the student loans:
Benefit-Cost Ratio = Present Worth of Additional Wages / Present Worth of Student Loans
Benefit-Cost Ratio = $57,977.10 / $30,000
Benefit-Cost Ratio = 1.93 (rounded to two decimal places)
