Question: Michael wants to dig a hole 400 feet less deep than twice the depth of the hole that his father dug. The father dug a hole at a rate of 4 feet per hour. If the father took 400 hours to dig his hole, how many hours will it take for Michael to dig a hole that is 400 feet less than twice as deep as his father's hole working at the same rate?
Answer: Since the father dug a hole with a rate of 4 feet per hour, if the father took 400 hours digging the hole, he dug a hole 4 * 400 = 1600 feet deep. Twice the depth of the hole that Michael's father dug is 2 * 1600 = 3200 feet. Michael wants to dig a hole 400 feet less than twice the depth of the hole that his father dug, meaning he wants to dig a hole 3200 - 400 = 2800 feet deep. To dig a hole that is 400 feet less than twice as deep as his father's hole working at a rate of 4 feet per hour, Michael will have to work for 2800 / 4 = 700 hours. The answer is 700.

Question: Marcia's hair is 24" long at the beginning of the school year. She cuts half of her hair off and lets it grow out 4 more inches. She then cuts off another 2" of hair. How long is her hair?
Answer: Her hair was 24" long and she cut half off so she cut 24 / 2 = 12 inches. Her hair was 24" long and she cut 12" off so she has 24 - 12 = 12 inches left. She has 12" of hair and lets it grow 4 more inches for a total of 12 + 4 = 16 inches. She has 16" and cuts off 2 more inches which leaves her hair 16 - 2 = 14 inches long. The answer is 14.

Question: Ben's new car cost twice as much as his old car. He sold his old car for $1800 and used that to pay off some of the cost of his new car. He still owes another $2000 on his new car. How much did his old car cost, in dollars?
Answer: His new car costs 1800 + 2000 = 3800 dollars. His old car cost 3800 / 2 = 1900 dollars. The answer is 1900.

Question: Free Christmas decorations are being given out to families. Each box of decorations contains 4 pieces of tinsel, 1 Christmas tree and 5 snow globes. If 11 families receive a box of decorations and another box is given to the community center, how many decorations have been handed out?
Answer:
Each box contains 4 tinsel + 1 tree + 5 snow globes = 10 decorations. A total of 11 family boxes + 1 community center box = 12 boxes have been given out. So the total number of decorations given out is 10 decorations * 12 boxes = 120 decorations. The answer is 120.
