Question: Jenna is hemming her prom dress. The dress's hem is 3 feet long. Each stitch Jenna makes is 1/4 inch long. If Jenna makes 24 stitches per minute, how many minutes does it take Jenna to hem her dress?
Answer: First find how many inches the hem is by multiplying the length in feet by the number of inches per foot: 3 feet * 12 inches / foot = 36 inches. Then divide the length in inches by the length of each stitch to find how many stitches Jenna makes: 36 inches / .25 inches = 144 stitches. Then divide the number of stitches by Jenna's stitching rate to find how long it takes her: 144 stitches / 24 stitches / minute = 6 minutes. The answer is 6.

Question: James decides to use tannerite to blow things up to reveal his baby's gender. The explosion ignites both his neighbors' houses and attracts a police officer, who arrests James on two count of arson, one count of manufacturing explosives, and one count of domestic terrorism. If the arson counts each carry a 6-year sentence, the explosives sentence is twice as long as the total arson sentence, and the domestic terrorism charge's sentence is 20 years, how long might James spend in jail?
Answer: First find the total sentence length for the arson: 6 years / count * 2 counts = 12 years. Then find the total sentence length for the explosives: 12 years * 2 = 24 years. Then add each sentence to find the total sentence length: 12 years + 24 years + 20 years = 56 years. The answer is 56.
Q: In my school, the number of students has increased by 20% this year. The number of students this year is 960. How many students were there last year?
A:
Let X be the number of students last year. The number of students this year is X + X * 20% = 960. Combining like terms, we get X * 1.2 = 960. Dividing both sides by 1.2, we get X = 800 students. The answer is 800.
