a. Write a set of detailed, step-by-step instructions in English to calculate the fewest number of dollar bills needed to pay a bill of amount TOTAL. For example, if TOTAL is $97, the bills would consist of one $50 bill, two $20 bills, one $5 bill, and two $1 bills. (For this exercise, assume that only $100, $50, $20, $10, $5, and $1 bills are available.)
b. Repeat Exercise 6a, but assume the bill is to be paid only in $1 bills.
