Alex Rodriguez recently signed a contract with the Texas Rangers that will pay him approximately 250 million dollars over the next 10 years. In this problem, assume that he will receive his pay annually in 25 million dollar installments, and that he has just received the first payment. Suppose that he decides to set aside a fixed amount each year to fund a perpetuity of 18500000 dollars per year for his retirement, with the first payment to come in 14 years. If the effective rate of interest is 7.6 percent, how much of his annual salary will be left, after he makes his perpetuity investment?
