Question: Linda was going to pass out homemade cookies to each of her 24 classmates on the last day of school. She wanted to give each student 10 cookies and wanted to make chocolate chip cookies and oatmeal raisin cookies. Each cookie recipe made exactly 4 dozen cookies. She was able to make 2 batches of chocolate chip cookies before running out of chocolate chips. She made 1 batch of oatmeal raisin cookies. How many more batches of cookies does Linda need to bake?
Answer: She has 24 classmates and wants to give each 10 cookies, so she needs to bake 24 * 10 = 240 cookies. Each batch makes 4 dozen cookies so that means each batch has 4 * 12 = 48 cookies. She baked 2 batches of chocolate chip and one batch of oatmeal raisin so 2 + 1 = 3 batches. We know that each batch has 48 cookies so 3 * 48 = 144 cookies have been baked. She needs to have 240 cookies and has baked 144 so 240 - 144 = 96 cookies are needed. Again, each batch makes 48 cookies and we need 96 more cookies so 96 / 48 = 2 more batches are needed. The answer is 2.

Q: A pipe is clogged so that only 2 ounces of cleaner can run through the pipe per minute. After fifteen minutes, the cleaner has unclogged it enough that 3 ounces can run through per minute. Ten minutes later, the clog is cleared enough for 4 ounces to run through per minute. How many ounces of cleaner were used after 30 minutes?
A: For 15 minutes at 2 ounces per minute, 2 * 15 = 30 ounces were used. For the next 10 minutes at 3 ounces per minute, 3 * 10 = 30 ounces were used. There are 30 - 15 - 10 = 5 minutes remaining. For the next 5 minutes at 4 ounces per minute, 4 * 5 = 20 ounces were used. After 30 minutes, 30 + 30 + 20 = 80 ounces of cleaner were used. The answer is 80.
Question: There is a lot of dust in Susie's house. It takes her 2 hours to vacuum the whole house. She can vacuum each room in 20 minutes. How many rooms does she have in her house?

[Question]Melinda is taking a 1200-mile trip with her family to visit their cousins. How much time will they save if they drive 60 miles an hour instead of 50 miles an hour?
[Answer]Going 60 mph, the trip would take 1200 - mile trip / 60 miles an hour = 20 hours. Going 50 mph, the trip would take 1200 - mile trip / 50 miles an hour = 24 hours. Melinda’s family would save 24 – 20 = 4 hours. The answer is 4.
