Q: Sara and Joe have a combined height of 120 inches. Joe is 6 inches more than double Sara's height. How tall is Joe?
A: Let x be Sara's height in inches. Joe is 6 + 2x inches tall. 120 = x + (6 + 2x). 120 = 3x + 6. 114 = 3x. x = 38 inches. Joe is 6 + 2(38) = 82 inches. The answer is 82.
Question: Debbie works at a post office packing boxes to mail. Each large box takes 4 feet of packing tape to seal, each medium box takes 2 feet of packing tape to seal, and each small box takes 1 foot of packing tape to seal. Each box also takes 1 foot of packing tape to stick the address label on. Debbie packed two large boxes, eight medium boxes, and five small boxes this afternoon. How much tape did she use?
Answer: Debbie used 4 * 2 = 8 feet of tape for the large boxes. She used 2 * 8 = 16 feet of tape for the medium boxes. She used 1 * 5 = 5 feet of tape for the small boxes. There were 2 + 8 + 5 = 15 boxes in all. She used 1 * 15 = 15 feet of tape for the address labels. Thus, she used 8 + 16 + 5 + 15 = 44 feet of tape in all. The answer is 44.

Q: Wendy spent 25 years as an accountant and 15 years as an accounting manager. If Wendy lived to be 80 years old, what percentage of her life did she spend in an accounting-related job?
A: First find the total number of years Wendy spent in accounting: 25 years + 15 years = 40 years. Then divide the number of years she spent in accounting by the number of years she lived and multiply by 100% to find the percentage of her life: 40 years / 80 years * 100% = 50%. The answer is 50.
Question: James visits 20 houses to try and make a sale. He manages to sell something in every house. The next day he visits twice as many houses but only sold to 80% of houses. If he sold two things at each house in each of the two days, how many items did he sell?
Answer: The second day he visited 20 * 2 = 40 houses. So he sold things at 40 * .8 = 32 houses. So in total he sold things at 20 + 32 = 52 houses. That means he sold 52 * 2 = 104 things. The answer is 104.
