Q: Hot dog buns come in packages of 8. For the school picnic, Mr. Gates bought 30 packages of hot dog buns. He has four classes with 30 students in each class. How many hot dog buns can each of Mr. Gates' students get?
A: Mr. Gates bought 30 x 8 = 240 hot dog buns. In his four classes, he has a total of 4 x 30 = 120 students. Therefore, each of his students can get 240 / 120 = 2 hot dog buns. The answer is 2.
Question: A supermarket has pints of strawberries on sale. They sold 54 pints and made $216, which was $108 less than they would have made selling the same number of pints without the sale. How many more dollars does a pint of strawberries cost when not on sale?
Answer: On sale, a pint of strawberries costs 216 / 54 = $4. The supermarket would have made 216 + 108 = $324 if the strawberries were not on sale. Thus, a pint of strawberries not on sale costs 324 / 54 = $6. Hence, a pint of strawberries costs 6 - 4 = $2 more when not on sale. The answer is 2.
[Question]Abigail has a report due tomorrow which needs to be 1000 words in length. Abigail can type 300 words in half an hour. If she has already written 200 words, how many more minutes will it take her to finish the report?
[Answer]She needs to type an additional 1000 – 200 = 800 words. In one minute she can type 300 words / 30 = 10 words. It will take her 800 / 10 = 80 more minutes to finish typing the report. The answer is 80.
Q: Rachel is an artist. She posts a speed painting video each week on her Instagram account to promote her work. To save time, she paints and records 4 videos at a time. It takes her about 1 hour to set up her painting supplies and her camera. Then she records herself painting for 1 hour per painting. She takes another 1 hour to clean up. Each video takes 1.5 hours to edit and post. How long does it take Rachel to produce a speed painting video?
A: Rachel spends 1 + 1 = 2 hours setting up and cleaning up. She paints for 1 hour x 4 paintings = 4 hours. Then she edits 1.5 hours x 4 videos = 6 hours. She spends 2 + 4 + 6 = 12 hours to make 4 videos. So Rachel spends 12 / 4 = 3 hours on each video. The answer is 3.
Question: When Mark bought his first tv it was was 24 inches wide and 16 inches tall. It cost $672. His new tv is 48 inches wide and 32 inches tall and costs $1152. How much more expensive as measure by cost per square inch, was his first TV compared to his newest TV?
Answer: His first TV was 384 square inches because 24 x 16 = 384. His first TV cost $1.75 per square inch because 672 / 384 = 1.75. His new TV is 1,536 square inches. It costs $.5 per square inch because 1152 / 1,536 = .5. His old TV cost $1 more per square inch because 1.75 - .75 = 1. The answer is 1.
Q: Brenda raises mice, and her adult mice recently had three litters of 8 each. She gave a sixth of the baby mice to her friend Robbie to keep as pets. She sold three times the number of babies she gave Robbie to a pet store. Half of the remaining mice were sold to snake owners as feeder mice. How many baby mice did Brenda have left?
A:
Brenda’s mice had 3 * 8 = 24 baby mice. She gave Robbie 24 / 6 = 4 mice. Thus, she sold 3 * 4 = 12 mice to the pet store. She had 24 - 12 - 4 = 8 mice remaining. She sold 8 / 2 = 4 as feeder mice. Thus, Brenda had 8 - 4 = 4 mice left. The answer is 4.
