Question: Max fills up water balloons for 30 minutes at a rate of 2 water balloons every minute. Max’s friend Zach fills up water balloons for 40 minutes at a rate of 3 water balloons every minute. In the process, 10 of the water balloons pop on the ground. How many filled water balloons do Max and Zach have in total?
Answer: Max fills 30 * 2 = 60 water balloons. Zach fills 40 * 3 = 120 water balloons. Max and Zach have a total of 60 + 120 - 10 = 170 water balloons. The answer is 170.

Question: Lorraine made a pan of brownies and cut them into 16 pieces. Her children ate 25% of the brownies when they got home from school. After dinner, the entire family ate 50% of the remaining brownies. After everyone went to bed, Lorraine ate 1 more brownie. How many brownies are left over?
Answer: Her children ate 25% of the 16 brownies so they ate .25 * 16 = 4 slices. There were 16 brownies and the children ate 4 slices, leaving 16 - 4 = 12 brownies. The family ate 50% of the remaining 12 brownies so they ate .50 * 12 = 6 brownies. There were 12 brownies and they ate 6 which leaves 12 - 6 = 6 brownies. Lorraine had 1 more of the 6 remaining brownies which leaves 6 - 1 = 5 brownies. The answer is 5.

Question: Pete has a bag with 10 marbles. 40% are blue and the rest are red. His friend will trade him two blue marbles for every red one. If Pete keeps 1 red marble, how many total marbles does he have after trading with his friend?
Answer:
He starts with 4 blue marbles because 10 x .4 = 4. 60% of the marbles are red because 100 - 40 = 60. He has 6 red marbles because 10 x .6 = 6. He trades 5 red marbles because 6 - 1 = 5. He gets 10 blue marbles because 5 x 2 = 10. He has 15 marbles now because 4 + 1 + 10 = 15. The answer is 15.
