[Question]Bruno wants to buy two and one-half dozens of pens. How many pens will he have?
[Answer]Since a dozen is equal to 12, then two dozens are equal to 12 x 2 = 24. One - half dozen is equal to 12 / 2 = 6. Thus, Bruno will have a total of 24 + 6 = 30 pens. The answer is 30.
Q: Calum runs a nightclub and decides to run a disco night to attract different customers. He is planning the event and is calculating how much he can spend on each item without spending more than he has budgeted. He only needs to buy 4 disco balls and 10 boxes of food. Each box of food costs $25. Calum’s budget for the disco balls and food is $330. How much, in dollars, can Calum afford to spend on each disco ball?
A: The food is going to cost Calum a total of 10 boxes of food * $25 per box of food = $250. This leaves $330 budget - $250 spent on food = $80 to spend on disco balls. Calum can therefore afford to spend $80 remaining budget / 4 disco balls = $20 on each disco ball. The answer is 20.
Question: Kelly, Brittany, and Buffy went swimming at Salt Rock Lake and held a contest to see who could hold their breath underwater for the longest amount of time. Kelly held her breath underwater for 3 minutes. Brittany held her breath underwater for 20 seconds less time than than Kelly did, and Buffy held her breath underwater for 40 seconds less time than Brittany did. How long, in seconds, did Buffy hold her breath underwater?
Answer: Kelly held her breath for 3 minutes, or 3 * 60 = 180 seconds. Brittany held her breath for 20 seconds less time than Kelly did, or 180 - 20 = 160 seconds. And Buffy held her breath for 40 seconds less time than Brittany did, or for 160 - 40 = 120 seconds. The answer is 120.
[Question]Robby doesn't like the color brown and will not eat the brown M&M's. On his first bag, he sets aside 9 brown M&M's. On the second bag, he sets aside 12. On his third & fourth bag, there are 8 brown M&M's that he doesn't eat. On his fifth bag, there are only 3 brown M&M's that he doesn't eat. What's the average number of brown M&M's in a bag?
[Answer]Out of 5 bags, he had 9 + 12 + 8 + 8 + 3 = 40 brown M&M's. He ate 5 bags so the average number of brown M&M's per bag was 40 / 5 = 8 brown M&M's. The answer is 8.

Question: Audrey's key lime pie calls for 1/4 cup of key lime juice but she likes to double this amount to make it extra tart. Each key lime yields 1 tablespoon of juice. There are 16 tablespoons in 1 cup. How many key limes does Audrey need?
Answer:
Her recipe calls for 1 / 4 cup of juice but she wants to double that so she needs 1 / 4 + 1 / 4 = 1 / 2 cup of lime juice. 16 tablespoons are in 1 cup and she only needs 1 / 2 cup so she needs 16 * .5 = 8 tablespoons of juice. 1 key lime yields 1 tablespoon of juice and she needs 8 tablespoons so she needs 1 * 8 = 8 key limes. The answer is 8.
