Q: Five coworkers were talking during the lunch break. Roger, the oldest one, said that he has the same amount of experience in years as all four of the others combined and that his retirement should come when he accumulates 50 years of experience. Peter said that when he came to the company his daughter was 7 years old, and now she is 19 years old. Tom then said he has twice as many years of experience as Robert. Robert said that he has 4 years of experience less than Peter but 2 more years of experience than Mike. How many more years does Roger have to work before he retires?
A: Peter has 19 – 7 = 12 years of experience. Robert has 12 – 4 = 8 years of experience. Mike has 8 – 2 = 6 years of experience. Tom has 2 * 8 = 16 years of experience. Roger has 12 + 8 + 6 + 16 = 42 years of experience. Roger has to work another 50 – 42 = 8 years before he retires. The answer is 8.

Q: Gina is participating in a neighborhood clean-up filling bags with litter. She was able to collect two bags of litter herself. The rest of the neighborhood together collected 82 times as much as Gina did by herself. Each bag of litter weighs 4 pounds. How many pounds was all the litter they collected?
A: The rest of the neighborhood collected 82 * 2 = 164 bags of litter. With Gina’s bags, they had 164 + 2 = 166 bags of litter. Thus, the litter weighed 166 * 4 = 664 pounds. The answer is 664.
