Question: 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?
Answer with step-by-step thinking: 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.
So the answer is 60.


Question: In Professor Plum's biology class there are 40 students. Of those students, 80 percent have puppies. Of those who have puppies, 25% also have parrots. How many students have both puppies and parrots?
Answer with step-by-step thinking: We start with the initial numbers of students, 40 and multiply that by .8 for 40 * 0.8 = 32 who own puppies. That the number of students with puppies, 32, and multiply that by .25 to find out how many own both puppies and parrots, 32 * 0.25 = 8 who own puppies and parrots. The answer is 8.
So the answer is 8.

At the start, Jeremy had two times more money than the price of the computer, which means he had 2 * 3000 = $6000. The cost of the accessories stands at 3000 * 1 / 10 = $300. This leaves Jeremy with 6000 - 3000 - 300 = $2700.
So the answer is 2700.
