Mrs. Petersons bought 10 tumblers for $45 each. She paid with five $100 bills. How much change will Mrs. Petersons receive?
The 10 tumblers amount to $45 x 10 = $<T>multiply(45, 10)=450
Mrs. Petersons paid $100 x 5 = $<T>multiply(100, 5)=500
So, her change will be $500 - $450 = $<T>subtract(500, 450)=50
