What is the equal annual amount of money you have to save to guarantee yourself an annual income to perpetuity of $55,000 starting in 42 years from now? You make the first payment in two years from now and the last payment in 42 years (i.e., you make payments at t = 2, 3, 4, ..., 42; and you will receive the first payment of the perpetuity at t = 42). Assume an interest rate of 7% (EAR). Please show all work and required formulas
