John is 30 years old at the beginning of the new millennium and is thinking about getting an MBA. John is currently making $40,000 per year and expects the same for the remainder of his working years (until age 65). If he goes to a business school, he gives up his income for two years and, in addition, pays $20,000 per year for tuition. In return, John expects an increase in his salary after his MBA is completed. Suppose that the post-graduation salary increases at a 5% per year and that the discount rate is 8%.

For simplicity, assume that all cash ows occur at the end of each year
