The Simpsons family are planning to make yearly deposits in an investment fund for the next 10 years. They want to use balance in their amount to start a family business at that time. They can afford to deposit $800 every two weeks. a. [5 pts] Assuming their investment fund receives an interest of 7% compounded bi-weekly (every two weeks), how much will they have in their account after 10 years. b. [4 pts] How much interest will be earned over the 10 years? c. [6 pts] If the Simpsons decide to deposit all of their savings (calculated in part a) in an account that will give them an interest rate of 12% compounded monthly instead of opening their family business. How much can they withdraw each month for 20 years in order to end up with a zero balance after the last withdrawal?
