Christine has $500 to deposit in a savings account, and she is trying to decide between two banks. Bank A offers 10%
annual interest compounded quarterly. Rather than compounding interest for smaller accounts, Bank B offers to add.
$15 quarterly to any account with a balance of less than $1,000 for every quarter, as long as there are no withdrawals.
Christine has decided that she will neither withdraw, nor make a deposit for a number of years.
Develop a model that will help Christine decide which bank to use.
