Q: Mike watches TV for 4 hours every day. On the days he plays video games he plays for half as long as he watches TV. If he plays video games 3 days a week how long does he spend watching TV and playing video games?
A: He plays video games for 4 / 2 = 2 hours a day. He watches TV for 4 * 7 = 28 hours a week. He plays video games for 3 * 2 = 6 hours. So in total he spends 6 + 28 = 34 hours on those activities. The answer is 34.

Q: 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.)
A: 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: Olga has three stripes on the side of each of her tennis shoes. Rick has one less stripe per shoe than does Olga. But Hortense has double the number of stripes on her tennis shoes as does Olga. In total, what is the combined number of stripes on all of their pairs of tennis shoes?
A:
Rick has one less than three stripes, or 3 - 1 = 2 stripes on each tennis shoe. Hortense has double the 3 stripes that Olga has, or a total of 3 * 2 = 6 stripes per shoe. Since each of them has two tennis shoes per pair, then the total number of stripes on all of their shoes is 2 * (3 + 2 + 6) = 22 stripes. The answer is 22.
