Reasoning and answer: Lena is 152 cm - 15 cm = 137 cm tall. Rebeca is 152 cm + 6 cm = 158 cm tall. So, the total height of Lena and Rebeca would be 137 cm + 158 cm = 295 cm.
The answer: 295

8 seasons with 15 episodes had 8 x 15 = 120 episodes. 4 seasons with 20 episodes had 4 x 20 = 80 episodes. 2 seasons with 12 episodes had 2 x 12 = 24 episodes. All together, there have been 120 + 80 + 24 = 224 episodes. The average number of episodes a year is 224 / 14 = 16 episodes.
The answer: 16
Reverse engineering the question: A TV show has been going on for 14 years. Out of those 14 years, 8 seasons had 15 episodes, 4 seasons had 20 episodes, and 2 seasons had 12 episodes. What is the average number of episodes per year?


Reasoning and answer: If there were 26 pink hard hats and Carl took away 4 pink hard hats, the number of pink hard hats that remained is 26 - 4 = 22. John also took away 6 pink hard hats, leaving 22 - 6 = 16 pink hard hats in the truck. If John also took twice as many green hard hats as pink hard hats, he took 2 * 6 = 12 green hard hats. The total number of green hard hats that remained in the truck is 15 - 12 = 3. In the truck, after some are taken, there were 3 green hard hats + 16 pink hard hats = 19 hard hats in the truck. Altogether, 19 green and pink hard hats + 24 yellow hards hats = 43 hard hats remained in the truck.
The answer: 43

Reasoning and answer: The sandbox has an area of 40 * 40 = 1600 square inches. To fill this area, 1600 / 80 = 20 bags of sand are needed. Then, the weight of these bags is 20 * 30 = 600 pounds.
The answer: 600

A father is buying sand to fill his son's new sandbox, but he is worried that the sand will be too heavy for his car. The sandbox is square, with each side being 40 inches long. If a 30-pound bag of sand is enough to fill 80 square inches of the sandbox to an adequate depth, how many pounds of sand are needed to fill the box completely?
