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.

Q: Mary sees three breeding balls with 8 snakes each and 6 additional pairs of snakes. How many snakes did she see total?
A: First find how many snakes were in all the breeding balls: 3 balls * 8 snakes / ball = 24 snakes. Then find how many snakes are in all the pairs: 2 snakes / pair * 6 pairs = 12 snakes. Then add the number of snakes in both types of groups to find the total number of snakes: 24 snakes + 12 snakes = 36 snakes. The answer is 36.
