1. Starting at age 20, Sarah Saver puts $300 each month into a retirement account that earns 6.5 percent APR, compounded monthly. At age 30 , Sarah stops saving and makes no further contributions. She lets the money grow at 6.5 percent APR compounded monthly for the next 40 years, until age 70 . Her friend, Steve Slacker, waits until age 30 before he starts saving a fixed amount each month. His investment will also earn 6.5 percent APR compounded monthly. If Sarah and Steve have the same amount saved for retirement at age 70, how much does Steve need to invest each month? Assume both Sarah and Steve deposit money at the end of each month
