Answer:
The will be 27000 bacteria in 36 hours from the start of the experiment
Step-by-step explanation:
In the first 18 hours:
The number of bacteria grew from 30 to 900.
So it grew by a factor of 900/30 = 30.
36 hours from the start of the experiment:
That is, the next 18 hours.
It will also grow by a factor of 30.
From 900 to 900*30 = 27000
The will be 27000 bacteria in 36 hours from the start of the experiment
4 yards x 36inches = 144
144/15inches=9.6
So the maximum is 9 ribbons with a little material left over.
