Creatively image a question and justification for this answer: 30
The question is: The price of buying a wooden toy at the new Craftee And Best store is $20, and the cost of buying a hat is $10. If Kendra went to the shop with a $100 bill and bought two wooden toys and three hats, calculate the change she received.
Step-by-step reasoning process: When Kendra bought 2 toys, she paid 2 * $20 = $40. Since the price of a hat is $10, when Kendra bought 3 hats, she paid 3 * $10 = $30. The total costs for the hats and wooden toys Kendra bought is $40 + $30 = $70. From the $100 bill, Kendra received change worth $100 - $70 = $30.
