Question: While preparing for a meeting, Bill fills Dixie cups with water from out of a water cooler. The water cooler initially contains 3 gallons of water, and each Dixie cup holds 6 ounces of water. If Bill fills one cup of water per each meeting chair, and there are 5 rows of meeting chairs with 10 chairs in each row, then how many ounces of water will be left in the cooler after all cups have been are filled? (There are 128 ounces in a gallon.)
Answer: First find the total number of ounces in the water cooler: 3 gallons * 128 ounces / gallon = 384 ounces. Then find the total number of dixie cups Bill pours: 5 rows * 10 chairs / row = 50 chairs. Then find the total number ounces Bill pours: 50 attendees * 6 ounces / attendee = 300 ounces. Then subtract the amount of water Bill pours from the cooler from the initial amount to find the final amount: 384 ounces - 300 ounces = 84 ounces. The answer is 84.

Q: 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?
A: 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. The answer is 6.
Question: Brian can only hold his breath underwater for 10 seconds. He wants to get better, so he starts practicing. After a week, he's doubled the amount of time he can do it. After another week, he's doubled it again from the previous week. The final week, he's increased it by 50% from the previous week. How long can Brian hold his breath for now?
Answer: At the end of his first week, Brian now has doubled his initial time of 10 seconds to 10 * 2 = 20 seconds. At the end of his second week, Brian doubled the previous week's time of 20 seconds to 20 * 2 = 40 seconds. At the end of his third week of practice, Brian adds another 50% of 40 seconds to his time so 40 * .5 = 20 seconds added. Having added 20 seconds to his time from his second week, Brian can now hold his breath for 40 + 20 = 60 seconds. The answer is 60.
