Q: Rita bought 5 short dresses, 3 pairs of pants and 4 jackets from a store that sells second-hand clothes. The dresses cost $20 each, the pants cost $12, the jackets cost $30 each, and she spent an additional $5 on transportation. If she had $400 initially, how much does she have now?
A: She bought 5 dresses at $20 each for a total of 5 * $20 = $100. She bought 3 pairs of pants at $12 each for a total of 3 * $12 = $36. She bought 4 jackets at $30 each for a total of 4 * $30 = $120. She spent an additional $5 on transportation for a sum total of $5 + $100 + $36 + $120 = $261. She initially had $400 so she now has $400 - $261 = $139. The answer is 139.

Q: There are 30 pieces of popcorn in a serving. Jared can eat 90 pieces of popcorn and his three other friends can each eat 60 pieces of popcorn. How many servings of popcorn should Jared order for all of them?
A: Jared's friends can eat a total of 60 x 3 = 180 pieces of popcorn. Jared and his three friends can eat a total of 180 + 90 = 270 pieces of popcorn. Therefore, Jared should order 270 / 30 = 9 servings of popcorn. The answer is 9.

Q: Tony has a bucket that holds 2 pounds of sand. He has a sandbox out back that is two feet deep, four feet wide, and 5 feet long. A cubic foot of sand weighs 3 pounds. Because it's hot outside, he wants to make sure he stays hydrated, so every 4 trips he takes he drinks 3 ounces of bottled water. A 15 ounce bottle of water costs $2. He has $10 with him. How much change will he have after he buys all the water he needs?
A:
The sandbox is 40 cubic feet because 2 x 4 x 5 = 40. He needs 120 pounds of sand because 40 x 3 = 120. He will take 60 trips because 120 / 2 = 60. He will need to drink water 15 times because 60 / 4 = 15. He will drink 45 ounces of water because 15 x 3 = 45. He will need 3 bottles of water because 45 / 15 = 3. He will spend $6 on water because 3 x 2 = 6. He will have $4 in change because 10 - 6 = 4. The answer is 4.
