You are considering two saving options. Both options offer a rate of rate of return of 11 percent. The first option is to save $2,500, $1,500, and $3,000 at the end of each year for the next three years, respectively. The other option is to save one lump sum amount today. You want to have the same balance in your savings account at the end of three years, regardless of the saving method you select. If you select the lump sum method, how much do you need to save today?
