Q: Tommy goes for a run around his neighborhood and decides to calculate how many wheels he saw. All the trucks in his neighborhood have 4 wheels and all the cars in his neighborhood also have 4 wheels. If he saw 12 trucks and 13 cars, how many wheels did he see?
A: He saw 25 total vehicles because 12 plus 13 equals 25. He saw 100 wheels because 25 times 4 equals 100. The answer is 100.
Question: Lenny bought 20 boxes of pens. Each box contained 5 pens. She gave 40% of the pens to her close friends and one-fourth of what's left to her classmates. How many pens were left for Lenny?
Answer: Lenny has 20 x 5 = 100 pens. She gave her close friends 100 x 40% = 40 pens. So, 100 - 40 = 60 pens were left. Half of 60 is 60 / 4 = 15 pens. Thus, Lenny has 60 - 15 = 45 pens left. The answer is 45.

Q: Savannah is wrapping presents for her friends and family for Christmas. She has bought 3 rolls of wrapping paper to wrap 12 gifts. If it takes 1 roll to wrap 3 gifts and 1 roll to wrap 5 other gifts, if there is no wrapping paper leftover after Savannah wraps the rest of the gifts, how many gifts did she wrap with the third roll of paper?
A: Savannah has 12 gifts to give her friends and family and has already wrapped 3 gifts + 5 gifts = 8 gifts already wrapped with the first two rolls of paper. She started off with 12 gifts to wrap and has already wrapped 8, 12 - 8 = 4 gifts she wraps with the third roll of paper. The answer is 4.
Question: Larry and Barry want to pick apples out of the tree, but neither is tall enough to reach the apples. Barry can reach apples that are 5 feet high. Larry is 5 feet tall, but his shoulder height is 20% less than his full height. If Barry stands on Larry's shoulders, how high can they reach?
Answer: Larry's shoulder height is 20% less than 5 feet, or 0.2 * 5 = 1 foot less than 5 feet. One foot less than 5 feet is 5 - 1 = 4 feet. If Barry stands on Larry's shoulders, they can reach 4 + 5 = 9 feet. The answer is 9.
Q: John gets lost on his way home. His normal trip is 150 miles and would take him 3 hours. He ends up driving 50 miles out of the way and has to get back on track. How long did the trip take if he kept the same speed?
A:
His speed is 150 / 3 = 50 mph. He was detoured 50 * 2 = 100 miles. So that adds 100 / 50 = 2 hours. So the total trip was 3 + 2 = 5 hours. The answer is 5.
