Q: Alex was having a cookout Friday night and planned to serve burgers to his guests. He planned to cook 3 burgers for each guest and had invited 10 friends over. 1 of his friends didn't eat meat and said they would bring their own food. Another one of his friends didn't eat bread and would not need the buns. The burger buns came 8 to a pack. How many packs of buns did Alex need to buy?
A: He invited 10 friends but he didn't need to cook for 1 of his friends so that left 10 - 1 = 9 friends to cook for. He was cooking 3 burgers per 9 guests so 3 * 9 = 27 burgers. He needed 27 burger buns but 1 guest wouldn't eat the buns so now he needs 27 - 3 = 24. He will need to buy 24 buns and they come 8 to a pack so he needs 24 / 8 = 3 packs of buns. The answer is 3.

Q: The big fashion show is being planned for next week. The show includes runway models strutting up and down the runway wearing designer clothing in front of an audience. There are two parts to the show: evening wear and bathing suits. It takes a model 2 minutes to walk out to the end of the runway and back, and models take turns, one at a time, walking the runway up and back, while wearing different clothes. If there are 6 models in the show, and each model will wear two sets of bathing suits and three sets of evening wear clothing during the runway portion of the show, how long will it take, in minutes, to complete all of the runway trips during the show?
A: 6 models wearing 2 sets of bathing suits, or a total of 6 * 2 = 12 trips wearing bathing suits. 6 models wearing 3 sets of evening wear, or a total of 6 * 3 = 18 trips wearing evening wear clothes. Altogether, there will be 12 + 18 = 30 trips up and down the runway. At 2 minutes per trip, all of the trips will take 30 * 2 = 60 minutes to complete. The answer is 60.
