Linda and Rob open an online savings account that has a 2.89% annual interest rate, compounded

sp2606 [1]

Answer:

FV= $34,222.33

Step-by-step explanation:

First, we need to calculate the weekly interest rate:

Weekly interest rate= 0.0289/52= 0.00056

To calculate the future value (FV), we need to use the following formula:

FV= {A*[(1+i)^n-1]}/i

A= weekly deposit

n= 15*52= 780

A= $35

FV= {35*[(1.00056^780) - 1]} / 0.00056

FV= $34,222.33
