Answer the following question.
A bear is preparing to hibernate for the winter and needs to gain 1000 pounds. At the end of summer, the bear feasts on berries and small woodland animals. During autumn, it devours acorns and salmon. It gained a fifth of the weight it needed from berries during summer, and during autumn, it gained twice that amount from acorns. Salmon made up half of the remaining weight it had needed to gain. How many pounds did it gain eating small animals?
Step-by-step reasoning process: The bear gained 1 / 5 * 1000 = 200 pounds from berries. It gained 2 * 200 = 400 pounds from acorns. It still needed 1000 - 200 - 400 = 400 pounds. Thus, it gained 400 / 2 = 200 pounds from salmon. Therefore, the bear gained 400 - 200 = 200 pounds from small animals.
The answer is 200.

Answer the following question.
Ann, Bill, Cate, and Dale each buy personal pan pizzas cut into 4 pieces. If Bill and Dale eat 50% of their pizzas and Ann and Cate eat 75% of the pizzas, how many pizza pieces are left uneaten?
Step-by-step reasoning process: In total, there are 4 x 4 = 16 pizza pieces. Bill and Dale eat 2 x 4 x 50% = 4 pieces. Ann and Cate eat 2 x 4 x 75% = 6 pieces. The four of them eat 4 + 6 = 10 pieces. There are 16 - 10 = 6 pizza pieces uneaten.
The answer is 6.

Step-by-step reasoning process: Maddie watches a total of 8 * 44 = 352 minutes of the TV show during the week. On Friday, she watches 2 * 44 = 88 minutes. On Monday, Thursday, and Friday, she watches 138 + 21 + 88 = 247 minutes. Thus, on the weekend she watches 352 - 247 = 105 minutes of the TV show.
The answer is 105.
