Every 6 hours, the amount of algae doubles. Therefore, after 18 hours, the algae will have doubled three times:
First doubling: 50 x 2 = 100 pounds
Second doubling: 100 x 2 = 200 pounds
Third doubling: 200 x 2 = 400 pounds
Therefore, the answer is A. 400.
First doubling: 50 x 2 = 100 pounds
Second doubling: 100 x 2 = 200 pounds
Third doubling: 200 x 2 = 400 pounds
Therefore, the answer is A. 400.
