[Question]Allen ordered five boxes of pizza, which cost $7 each box. He then gave a tip which amounts to 1/7 of the total cost of his order. If he gave the delivery man $100, how much change did he receive?
[Answer]The total cost of five boxes of pizza is $7 x 5 = $35. He gave $35 x 1 / 7 = $5 tip to the delivery man. He spent a total of $35 + $5 = $40 for the pizza and the tip. The change that he received is $100 - $40 = $60. The answer is 60.
Q: Stephen ordered 2 large pizzas, both cut into 12 slices. He ate 25% of the pizza. His friend Pete ate 50% of the remaining pizza. How many slices are left over?
A: He ordered 2 pizzas, each cut into 12 slices so that’s 2 * 12 = 24 slices. Stephen ate 25% of the pizza so he ate .25 * 24 = 6 slices. That leaves 24 - 6 = 18 slices. 18 slices are left and Pete eats 50% of 18 slices so he eats 18 * .50 = 9 slices. If there were 18 slices and Pete ate 9 slices then there are 18 - 9 = 9 slices left over. The answer is 9.
