Suppose Chris plans to save for retirement over the next 15 years by making equal incremental savings payment at the end of each semiannual period beginning six months from today. When he retires, in 15 years, he will begin withdrawing $4,441 at the end of each semiannual period and anticipates that retirement will last for 27 . How much will Chris need to save each semiannual period from now until year 15 to fund his retirement if the interest rate is 6.88% (Hint, this is a two step problem, 1) how much will he need to have saved to fund his retirement, 2) how much will he need to save to get there) Answer Format: INCLUDE ONLY NUMBERS AND DECIMALS IN YOUR ANSWER.
