[Question]The difference in ages between Richard and Hurley is 20. If Hurley is 14 years old, what are their combined ages 40 years from now?
[Answer]If Hurley is 14 years old, and the difference in ages between Richard and Hurley is 20, Richard is 20 + 14 = 34. Forty years from now, Hurley will be 14 + 40 = 54 years old. Richard will be 40 + 34 = 74 years forty years from now. Their combined ages forty years from now will be 74 + 54 = 128 years. The answer is 128.
Q: Cary is saving money to buy a new pair of shoes that cost $120. He has already saved $30. He earns $5 for every lawn he mows. If he mows 3 lawns each weekend, how many more weekends will he have to mow lawns before he can afford to buy the shoes?
A: Cary needs to save an additional $120 - $30 = $90. Cary makes $5 * 3 = $15 each weekend. It will take 90 / 15 = 6 more weekends to save enough money to afford the shoes. The answer is 6.

[Question]Mr. Willson worked on making his furniture for 3/4 an hour on Monday. On Tuesday, he worked for half an hour. Then he worked for 2/3 an hour on Wednesday and 5/6 of an hour on Thursday. If he worked for 75 minutes on Friday, how many hours in all did he work from Monday to Friday?
[Answer]Since there are 60 minutes in an hour, then Mr. Willson worked for 60 minutes x 3 / 4 = 45 minutes on Monday. He worked for 60 minutes / 2 = 30 minutes on Tuesday. He worked for 60 minutes x 2 / 3 = 40 minutes on Wednesday. He worked for 60 minutes x 5 / 6 = 50 minutes on Thursday. So Mr. Willson worked for 45 + 30 + 40 + 50 + 75 = 240 minutes. In hours, it is equal to 240 / 60 = 4 hours. The answer is 4.

Question: Mark builds an apartment that is 16 by 10 feet. There are 6 rooms in total. All the rooms are the same size except the living room which is as big as 3 other rooms. How big is the living room?
Answer:
Total square footage is 16 * 10 = 160 square feet. . There are 3 + 3 = 6 rooms. 6 - 1 = 5 of them are the same size. If x is the size of the normal room then the square footage of all rooms is 5x + 3x = 8x. So each room is 160 / 8 = 20 square feet. So the living room is 20 * 3 = 60 square feet. The answer is 60.
