Question: If we look at the formula to calculate the dollar amount of a $1 we put into savings today, we see that it is \(fv=pv{{\left( 1+i \right)}^{n}}\). The variables are fv = future value, pv = present value, i = interest rate per period, and n = number of periods. In the formula, n is an exponent. What does the exponent in this case tell us we need to do mathematically to the (1 + i ) segment of the formula? Select a different interest rate ( i ) than your classmates who have already answered this question, as well as a different number of periods ( n ). How much money would you have at the end if you invested $1 today ( pv )?
