Question: Two days ago, the temperature in the morning went up 1.5 degrees every 2 hours. If the temperature was 50 degrees at 3 A.M., what was the temperature at 11 A.M.?
Answer: At 5 A.M., the temperature was 50 degrees + 1.5 degrees = 51.5 degrees. At 7 A.M., the temperature was 51.5 degrees + 1.5 degrees = 53 degrees. At 9 A.M., the temperature was 53 degrees + 1.5 degrees = 54.5 degrees. At 11 A.M., the temperature was 54.5 degrees + 1.5 degrees = 56 degrees. The answer is 56.
[Question]Mr. Salazar had seven dozen oranges. He reserved 1/4 of it for his friend and was able to sell 3/7 of the remaining yesterday. Today, he saw four rotten oranges. How many oranges are left to be sold today?
[Answer]Mr. Salazar had 7 x 12 = 84 oranges. He reserved 84 x 1 / 4 = 21 oranges for his friend. Ha had 84 - 21 = 63 oranges to be sold yesterday. But only 63 x 3 / 7 = 27 oranges were sold yesterday. So, he had 63 - 27 = 36 oranges left. Since four oranges are rotten, then only 36 - 4 = 32 oranges are left to be sold today. The answer is 32.

Question: 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?
Answer: 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.
