Reasoning and 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: 30

Question: Bruno wants to buy two and one-half dozens of pens. How many pens will he have?


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: 20
Reverse engineering the question: 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?


Reasoning and 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: 120

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: 8
Reverse engineering the 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.

Reasoning and 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: 8
