A debt of $3500 due in four years and $5000 due in six years is to be repaid by a single payment of $1500 now and three equal payments that are due at the end of each consecutive year from now. If the interest rate is 7% compounded annually, how much are each of the equal payments?

题目的意思是：一个要4年还清$3500和6年还清的$5000的债务将提速到现在支付
$1500并且从现在起连续3年的年末支付同样的费用。如果年复利率是7％，则每次相等的费用是多少？
解：设每次x美元，则有1500＋x（1＋7％）3次方＝3500（1＋7％）4次方＋5000（1+7%)6次方
解得x＝8645.77美元
但愿是没错！
