Beau Barrett · Answer 1

50*2=100 100*2=200 200*2=400

So there would be 400 pounds off algae in 9 hours

Charlize Gross · Answer 2

400 pounds because after the first three hours you have 100 pounds and after the second three hours you have 200 pounds now you're at 6 hours and than after the third three hours you have 400 pounds after 9 hours
