Answer :
Answer:
400
Step-by-step explanation:
12 divided by 4 equals 3 periods where the amount of algae doubles. so from 0-4 hours the algae doubles to 100 , at 4-8 the algae doubles to 200, and then doubles to 400
So it starts with 50lbs of algae And it doubles every 4 hours. 12 hours is it doubling three times so 50 doubled is 100 the 100 doubled is 200 and after 12 hours 200 doubled would be 400lbs algae.
