Business Week publishes rankings of the best business schools. The number one ranked school was the Wharton School at the University of Pennsylvania. The tuition at Wharton is $$25,000/$year$.$ The average pre$-$MBA salary among those attending Wharton is $$45,000$ and the Post$-$MBA salary is $$100,000.$ It takes two years to obtain an MBA. Assume that you are expecting to earn the average salary starting next year $($$$45,000)$ and will earn that same salary until you retire if you keep working, and that you expect to earn the average post$-$MBA salary after you get an MBA. Assume that the required rate of return is $10\%.$ You are considering enrolling in an MBA program that starts next year, if you decide to enroll, you'll have to pay the first year tuition right now, and year $2\text{'}$s tuition in year $1.$ You will also be unable to work during the $2$ years that you persue your MBA.

Assume that you will work for a total of $32$ years before retirement.
