A.J. plans to pay his child's tuition fee for four years starting 15 years from now. He estimates the fees is $22,000 per year. If the saving account interest rate is 5.5% annually, and how much payment A.J. should make at the end of each year from now?
Step 1: N = 4, FV = 0, I/Y = 5.5, PMT = 22,000, CPT PV = -77,113.30
Step 2: PV =0, N = 14, I/Y = 5.5, FV = 77,113.30, CPT PMT =-$3,800.07
步骤2里面 N为什么等于4 不是说的从现在起15年吗 为什么不是等于15
