Question

Suppose that the amount of algae in a pond dobles every 6 hours. If the pond initially contains 50 ponds of algae, how much algae would be in the pond in 18 hours?
a. 400
b. 10,800
c. 300
d. 600

Answer 1

Well we know the algae doubles three times.
So take 50 x 2 = 100
take 100 x 2= 200
200 x 2 = 400

So the answer is A
