(Complex annuity and future value) Milhouse, 25, is about to begin his career as a rocket scientist for a NASA contractor. Being a rocket scientist, Milhouse knows that he should begin saving for retirement immediately. Part of his inspiration came from reading an article on Social Security in Newsweek, where he saw that the ratio of workers paying taxes to retirees collecting checks will drop dramatically in the future. In fact, the ratio was 8.6 workers for every retiree in 1955; today the ratio is 3.0, and it will drop to 2 workers for every retiree in 2035. Milhouse's retirement plan pays 14 percent interest annually and allows him to make equal yearly contributions. Upon retirement, Milhouse plans to buy a new boat, which he estimates will cost him $280,000 in 35 years (he plans to retire at age 60). He also estimates that in order to live comfortably, he will require a yearly income of $90,000 for each year after he retires. Based on family history, Milhouse expects to live until age 90 (that is, he would like to receive 30 payments of $90,000 at the end of each year). When he retires, Milhouse will purchase his boat in one lump sum and place the remaining balance of his savings into an account, which pays 7% interest, from which he will withdraw his $90,000 per year. If Milhouse's first contribution is made 1 year from today, and his last is made the day he retires, how much money must he contribute each year to his retirement fund? a. In order for him to withdraw 30 payments of $90,000 at the end of each year after he retires, how much money will Milhouse need to have in the retirement account earning 7% when he retires? (Round to the nearest cent.) b. Upon retirement, Milhouse also plans to buy a new boat, which he estimates will cost him $280,000 in 35 years. How much money should Milhouse have in the retirement fund to achieve the goal when he retires? (Round to the nearest cent.) c. Milhouse, 25, is about to begin saving for retirement immediately.
