Question: Celina enjoys hiking in the mountains. Due to a lack of proper equipment, she decided to order a new pair of boots, a flashlight, and a special hoodie. The hoodie cost $80 and the flashlight was only 20% of that price. The pair of boots cost was $110, but due to a special promotion, Celina was able to buy them 10% cheaper. How much did Celina spend in total on the above-mentioned equipment?
Answer: The flashlight was 20% of the price of the hoodie, so 80 * 20 / 100 = $16. The promotion for a pair of boots was 110 * 10 / 100 = $11. So the pair of boots cost 110 - 11 = $99. Celina therefore spent 80 + 16 + 99 = $195 on the equipment. The answer is 195.
[Question]Grace is filling her pool in the backyard with a hose that sprays 50 gallons/hour. She waited for 3 hours but the pool wasn't full, so she decides to add another hose that sprays 70 gallons/hour, and after 2 more hours the pool is full. How much water can Grace’s pool contain?
[Answer]In the first 3 hours the pool gets 50 gallons / hour x 3 hours = 150 gallons. With the addition of the other hose, the pool was filling with a rate of 50 gallons / hour + 70 gallons / hour = 120 gallons / hour. In the next 2 hours with both hoses the pool gets 120 gallons / hour x 2 hours = 240 gallons. The pool's total capacity is 240 gallons + 150 gallons = 390 gallons. The answer is 390.
Q: James has 3 gallons of milk. He drank 13 ounces of the milk. If there are 128 ounces in a gallon, how many ounces of milk does James have left?
A: First find out how many ounces of milk James had to begin with by multiplying the number of gallons by the number of ounces per gallon: 3 gallons * 128 ounces / gallon = 384 oz. Now subtract the 13 ounces James drank from the initial amount of milk: 384 oz - 13 oz = 371 oz. The answer is 371.
Question: Billy and Tiffany are having a contest to see how can run the most miles in a week. On Sunday, Monday, and Tuesday, Billy runs 1 mile each day and Tiffany runs 2 miles each day. On Wednesday, Thursday, and Friday, Billy runs 1 mile each day and Tiffany runs a 1/3 of a mile each day. On Saturday Tiffany assumes she's going to win and takes the day off. How many miles does Billy have to run on Saturday to tie Tiffany?
Answer: Billy has already run 6 miles because 1 plus 1 plus 1 plus 1 plus 1 plus plus 1 equals 6. Tiffany has already run 7 miles because 2 plus 2 plus 2 plus 1 / 3 plus 1 / 3 plus 1 / 3 equals 7. Billy has to run 1 mile to tie Tiffany because 7 minus 6 equals 1. The answer is 1.
[Question]John raises butterflies. He has 4 jars of 10 caterpillars each. 40% of them fail to become butterflies, but the rest become caterpillars.  He sells the butterflies for $3 each. How much money does he make?
[Answer]He has 4 * 10 = 40 caterpillars. 40 * .4 = 16 fail to form. That means he has 40 - 16 = 24 butterflies. So he makes 24 * 3 = $72. The answer is 72.
