[Question]Cathy and Chris got summer jobs at the cake shop and were supposed to work 20 hours per week each for 2 months. During that time, Chris got sick for one week and Cathy took her shifts. If there are four weeks in a month, how many hours did Cathy work during the 2 months?
[Answer]There are 4 weeks in a month so Cathy and Chris were supposed to work for 4 weeks / month x 2 months = 8 weeks each. Since Chris got sick then Chris was only able to work for 8 weeks - 1 week = 7 weeks while Cathy worked for 8 weeks + 1 week = 9 weeks. Therefore, Cathy worked for 9 weeks x 20 hours / week = 180 hours. The answer is 180.

[Question]Carla has 6 sunflowers and 8 dandelions. The sunflowers have 9 seeds per plant and the dandelions have 12 seeds per plant. What percentage of Carla's seeds come from the dandelions?
[Answer]First calculate the number of seeds from the sunflowers by multiplying the number of sunflowers by the number of seeds per sunflower: 6 sunflowers * 9 seeds / sunflower = 54 seeds. Next calculate the number of seeds from the dandelions by multiplying the number of dandelions by the number of seeds per dandelion: 8 dandelions * 12 seeds / dandelion = 96 seeds. Now add the number of seeds from each group of plants to find the total number of seeds: 54 seeds + 96 seeds = 150 seeds. Now divide the number of dandelion seeds by the total number of seeds and multiply the answer by 100 to find the percentage of seeds that come from the dandelions: 96 seeds / 150 seeds * 100% = 64%. The answer is 64.

[Question]Bill is trying to decide whether to make blueberry muffins or raspberry muffins. Blueberries cost $5.00 per 6 ounce carton and raspberries cost $3.00 per 8 ounce carton. If Bill is going to make 4 batches of muffins, and each batch takes 12 ounces of fruit, how much money would he save by using raspberries instead of blueberries?
[Answer]First find how many ounces of fruit Bill will need total: 12 ounces / batch * 4 batches = 48 ounces. Then find how many cartons of blueberries Bill would need: 48 ounces / 6 ounces / carton = 8 cartons. Then multiply that number by the cost per carton to find the total cost of the blueberries: 8 cartons * $5 / carton = $40. Then find how many cartons of raspberries Bill would need: 48 ounces / 8 ounces / carton = 6 cartons. Then multiply that number by the cost per carton to find the total cost of the raspberries: 6 cartons * $3 / carton = $18. Then subtract the cost of the raspberries from the cost of the blueberries to find the difference: $40 - $18 = $22. The answer is 22.

[Question]Martin has 18 goldfish. Each week 5 goldfish die. Martin purchases 3 new goldfish every week. How many goldfish will Martin have in 7 weeks?
