Suppose that the amount of algae in a pond doubles every 4 hours. If the pond initially

Question

contains 50 pounds of algae, how much algae will be in the pond after 12 hours?

Answer 1

Let's start with the initial amount of algae in the pond, which is 50 pounds.

After 4 hours, the amount of algae in the pond will double to 50 * 2 = 100 pounds.

After 8 hours, the amount of algae in the pond will double again to 100 * 2 = 200 pounds.

After 12 hours, the amount of algae in the pond will double once more to 200 * 2 = 400 pounds.

Therefore, after 12 hours, there will be 400 pounds of algae in the pond.
