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.
Suppose that the amount of algae in a pond doubles every 4 hours. If the pond initially
contains 50 pounds of algae, how much algae will be in the pond after 12 hours?
