Q: Hayden eats 1 oz of mixed nuts as an evening snack. He buys the bulk bag of mixed nuts that cost $25.00 a bag and holds 40 oz of mixed nuts. There is currently a $5.00 coupon for this item. How much will each serving of nuts cost, in cents, after the coupon is applied?
A: The nuts are $25.00 and he has a $5.00 coupon, so the nuts are on sale for $25 - $5 = $20.00. He eats 1 oz of nuts every evening and the bag has 40 oz of nuts, so it has 40 / 1 = 40 1 oz servings. The nuts cost $20.00 and there are 40 servings per bag, so his snack is $20 / 40 = $0.50 per serving. The answer is 50.

Q: A used car lot has 24 cars and motorcycles (in total) for sale. A third of the vehicles are motorcycles, and a quarter of the cars have a spare tire included. How many tires are on the used car lot’s vehicles in all?
A: The used car lot has 24 / 3 = 8 motorcycles with 2 tires each. The lot has 24 - 8 = 16 cars for sale. There are 16 / 4 = 4 cars with a spare tire with 5 tires each. The lot has 16 - 4 = 12 cars with 4 tires each. Thus, the used car lot’s vehicles have 8 * 2 + 4 * 5 + 12 * 4 = 16 + 20 + 48 = 84 tires in all. The answer is 84.

Q: Kelly booked a three week vacation to visit relatives. The first day, she spent traveling. The next 5 days she spent at her Grandparents' house. The next day, she spent traveling. Then, she spends the next 5 days at her brother's house. Then she spent two days traveling to her sister's house, spent several days at her sister's house, and then spent two more days traveling home. How many days did she spend at her sister's house?
A:
Three weeks is 7 * 3 = 21 days. She traveled one day to her grandparents' house, one day to her brother's house, two days to her sister's house, and two days back home for a total of 1 + 1 + 2 + 2 = 6 days. She spent 5 days at her grandparents' house and 5 days at her brother's house, for a total of 5 + 5 = 10 days. Thus, of the 21 vacation days, the number of days remaining to spend with her sister was 21 - 6 - 10 = 5 days. The answer is 5.
