Question: Harry owns 3 geckos, 2 iguanas, and 4 snakes. If he spends $10 to feed each snake, $5 to feed each iguana, and $15 to feed each gecko every month, how much does he spend every year to feed all his pets?
Answer: He spends $10 / snake * 4 snakes = $40 to feed his snakes every month. He spends $5 / iguana * 2 iguanas = $10 to feed his iguanas every month. He spends $15 / gecko * 3 geckos = $45 to feed his geckos every month. So overall he spends $40 + $10 + $45 = $95 to feed all his pets every month. Therefore every year pet food costs him $95 / month * 12 months = $1140. The answer is 1140.
[Question]Lily has 5 lottery tickets to sell. She sells the first ticket for $1. She then sells each successive ticket for a dollar more than the previous ticket. She plans to keep a $4 profit and give the remaining money as the prize. How much money will the winner of the lottery receive?
[Answer]The second ticket sold will cost $1 + $1 = $2. The third ticket sold will cost $2 + $1 = $3. The fourth ticket sold will cost $3 + $1 = $4. The fifth ticket sold will cost $4 + $1 = $5. The total money collected is $1 + $2 + $3 + $4 + $5 = $15. After taking profit, the total prize money will be $15 - $4 = $11. The answer is 11.

A: He uses 3 detergent pods a week and there are 52 weeks in a year, so he uses 3 * 52 = 156. His detergent has 39 pods per pack and he needs 156 pods, so he will need 156 / 39 = 4 packs of detergent pods. The answer is 4.
Question: Keiko sent 111 text messages last week. This week she sent 50 less than double what she sent last week. How many text messages did Keiko send last week and this week combined?

Q: Marcy is the lunch monitor in an elementary school cafeteria. She gives 5 time-outs for running, 1 less than five times that number of time-outs for throwing food, and 1/3 the number of food-throwing time-outs for swearing. If each time-out is 5 minutes, how much time do the students spend in time-out total?
A:
First multiply the number of running time - outs by 5: 5 time - outs * 5 = 25 time - outs. Then subtract 1 from that number to find the number of food - throwing time - outs: 25 time - outs - 1 = 24 time - outs. Then divide that number by 3 to find the number of swearing time - outs: 24 time - outs / 3 = 8 time - outs. Then add the number of each kind of time - out to find the total number: 8 time - outs + 24 time - outs + 5 time - outs = 37 time - outs. Then multiply that number by the length of each time - out to find the total time the students spend in time - out: 37 time - outs * 5 minutes / time - out = 185 minutes. The answer is 185.
