Question: At a garage sale, Tish bought 4 items: a red horseshoe magnet, two stuffed animals, and a large sticker which read, "Why can't teachers solve their own math problems?" The magnet cost three times more than the sticker, but only one quarter the price of the two stuffed animals combined. If the Magnet cost $3, how much, in dollars, did a single stuffed animal cost?
Answer with step-by-step thinking: If the magnet cost 3 - times more than the sticker, the sticker cost 3 / 1 = 1 dollar. If the magnet cost 1 / 4 the price of the two stuffed animals combined, then two stuffed animals cost 3 * 4 = 12 dollars. Thus, a single stuffed animal cost 12 / 2 = 6 dollars.
So the answer is 6.

Question: John sublets his apartment to 3 people who each pay $400 per month. He rents the apartment for $900 a month. How much profit does he make in a year?
Answer with step-by-step thinking: He gets 3 * $400 = $1200 per month. So he gets 1200 * 12 = $14,400 per year. So he pays 12 * 900 = $10800 a year. That means his profit is 14400 - 10800 = $3600 per year.
So the answer is 3600.

Question: Mr. Johnson has a prescription with enough pills for 30 days. After four-fifths of the days, he has 12 pills left. How many pills is Mr. Johnson supposed to take a day if he takes the same dose daily?
Answer with step-by-step thinking:
Mr. Johnson has been taking the pills for 30 * 4 / 5 = 24 days. He has 30 - 24 = 6 days left to finish the pills. Thus, Mr. Johnson is supposed to take 12 / 6 = 2 pills a day.
So the answer is 2.
