**Question description**

If you look at the formula to calculate the dollar amount of $1 you put into savings today, you see that it is fv = pv*((1+i)^n). The variables are fv = future value, pv = present value, i = interest rate per period, and n = the number of periods. In the formula, n is an exponent.

*What does the exponent in this case state that you need to do mathematically to the (1 + i) segment of the formula?

*Select an interest rate as well as a different number of periods.

*How much money would you have at the end if you invested $1 today (pv)?
