We have a question: Justin wanted to watch a movie that came on at 8 pm that night. His parents agreed as long as he finished his homework and chores before the movie started. He wouldn't be home until 5 pm because of baseball practice. He knew dinner would take 45 minutes, and he figured his homework would take 30 minutes to finish. He needed to clean his room, which would take 30 minutes; then take out the trash, which would take about 5 minutes; and empty the dishwasher, which would take another 10 minutes. What was the latest time that Justin could start his chores and homework to be done by 8 pm to watch his movie?
And an answer: 6
So how you got the answer?
Justin would spend 45 minutes at dinner, 30 minutes doing homework, 30 minutes cleaning his room, 5 minutes on the trash and 10 on dishes for a total of 45 + 30 + 30 + 5 + 10 = 120. Justin knows that 60min is the same as 1 hour. He has 120 minutes of work so 120 / 60 = 2 hours. His movie comes on at 8 pm and he has 2 hours of chores so 8 - 2 = 6 pm is the latest time he could start his chores.

We have a question: Doris works at the Widget Factory in the packing department. She puts 3 widgets in each carton, which are 4 inches wide, 4 inches long, and 5 inches tall. She then packs those cartons into a shipping box before sending it to the loading bay. The shipping boxes are 20 inches wide, 20 inches long, and 20 inches high. How many widgets get shipped in each shipping box?
And an answer: 300
So how you got the answer?
Each carton has an area of 4 * 4 * 5 = 80 square inches. Each shipping box has an area of 20 * 20 * 20 = 8000 square inches. The total number of cartons that will fit into each box is 8000 / 80 = 100. Since there are 3 widgets in each carton, the total number of cartons in each box will be 3 * 100 = 300.

We have a question: Marge planted 23 seeds in her garden. Five of the seeds never grew into plants. A third of the remaining seeds grew, but the plants were eaten by squirrels and rabbits. A third of the number of uneaten plants were strangled by weeds. Marge pulled two weeds, but liked the flowers on one weed and let the plant grow as part of her garden. How many plants did Marge end up with?
And an answer: 9
So how you got the answer?
Marge had 23 - 5 = 18 seeds grow into plants. Rabbits ate 18 / 3 = 6 plants. There were 18 - 6 = 12 plants left. Weeds strangled 12 / 3 = 4 plants. She had 12 - 4 = 8 plants left. Marge kept 1 weed, so she ended up with 8 + 1 = 9 plants.
