The Tagovailoa brothers are making deposits in their respective investment accounts. In 15 years, Tua and his sibling Taulia would each like to have a $22,500 balance in their respective accounts. We are going to assume that Tua (who is in the NFL) earns an annual return of 10.9 percent whereas Taulia (who is still an undergraduate at Maryland) only earns 9.4 percent. If these assumptions are correct, how much less than Taulia will Tua have to deposit today?
