Mrs. Petersons bought 10 tumblers for $45 each. She paid with five $100 bills. How much change will Mrs. Petersons receive?
Thoughts? Step-by-step reasoning:
The 10 tumblers amount to $45 x 10 = $450. Mrs. Petersons paid $100 x 5 = $500. So, her change will be $500 - $450 = $50.
Thus, the answer is 50.
