Suppose that the amount of algae in a pond doubles every 4 hours. If the pond initially contains 90 pounds of algae, how much algae will be in the pond after 12 hours?%0D%0A(1 point)%0D%0AResponses%0D%0A%0D%0A720 pounds%0D%0A720 pounds%0D%0A%0D%0A360 pounds%0D%0A360 pounds%0D%0A%0D%0A1,440 pounds%0D%0A1,440 pounds%0D%0A%0D%0A114 pounds
The amount of algae doubles every 4 hours, so after 12 hours, it doubles 3 times.
Initially, there are 90 pounds of algae.
After 4 hours, there will be 90 * 2 = 180 pounds of algae.
After 8 hours, there will be 180 * 2 = 360 pounds of algae.
After 12 hours, there will be 360 * 2 = 720 pounds of algae.
The correct answer is 720 pounds.
