Answer:
The answer is 9 hours
Step-by-step explanation:
From the initial population of 180 cells, the number grows by 8% every hour for the first 9 hours.
This represents a increased population of 108% the previous population.
108% = 108/100 = 1.08
So the new population after n hours is
180 x 1.08^n
When population is 360
360 = 180 x 1.08^n
1.08^n = 2
Take log of both sides
n x Log1.08 = Log 2
n = Log 2/Log 1.08
n = 9

Lets say a balloon = x
4x + 5x + 6x = 120
15x = 120 (divide each side by 15)
15x/15 = 120/15
x = 8
blue balloons = 4x = 4(8) = 32
red balloons = 5x = 5(8) = 40
yellow balloons = 6x = 6(8) = 48
