Question: Mitzel spent 35% of her allowance. If she spent $14, how much money is left in her allowance?
Answer with step-by-step thinking: If 35% represents 14, then 100 - 35 = 65 represents the amount left of her allowance. The amount she didn't use is 65 * 14 / 35 = 26.
So the answer is 26.


Question: Sandra had 2 different bags of candy. Each of her bags had 6 pieces of candy left. Her brother, Roger, also had 2 bags of candy. One of his bags of candy had 11 pieces left and the other had 3 pieces left. How much more candy did Roger have?
Answer with step-by-step thinking: Sandra had 2 bags that each contained 6 pieces of candy so 2 * 6 = 12 pieces. Roger had 11 pieces of candy in one bag and 3 pieces in the other so 11 + 3 = 14 pieces. Roger had 14 pieces and Sandra had 12 pieces so Roger has 14 - 12 = 2 more pieces of candy.
So the answer is 2.
