Question: Four small panda bears and five bigger panda bears eat 25 pounds and 40 pounds of fresh bamboo sprouts every day, respectively. How many pounds of bamboo do the 9 pandas eat in a week?
Answer: The small panda bears eat a total of 4 x 25 = 100 pounds of bamboo every day. The bigger panda bears eat a total of 5 x 40 = 200 pounds of bamboo every day. So, the 9 pandas eat a total of 100 + 200 = 300 pounds of bamboo every day. Therefore, they eat a total of 300 x 7 = 2100 pounds in a week. The answer is 2100.
