Question

A bill for $9.37 is paid with a $5 bill, five $1 bills, one nickel, and two pennies. How much change should be given back?

Answer 1

First, lets add them all up.
5.00 + 5.00 + 0.05 + 0.02 = $10.07 <-- how much you gave him. Since the bill is $9.37 and you paid $10.07, to get the change just use subtraction. $10.07 - $9.37 = $0.70 <-- That's how much change should be given back!

Final answer = 0.70

Answer 2
