A bank that provides overdraft protection charges $12$ percent for each $$100($or portion of $$100)$ borrowed when an overdraft occurs.

What amount of interest would the customer pay for a $$440$ overdraft? $($Assume the interest is for the full amount borrowed for a whole year.$)$

How much would be saved by using the overdraft protection loan if a customer has five overdraft charges of $$45$ each during the year?
