Answer:
18 bacteria
Step-by-step explanation:
The formula for Exponential growth is given as:
y = a (1 + r)^t
a = Initial sample size = 5
y = Sample size after time t
r = Growth rate = 6% = 0.06
t = Time in hours = 22
Hence,
y = 5 (1 + 0.06)²²
y = 5 × 3.6035374165783565
y =18.017687083 bacteria
Approximately = 18 bacteria
Therefore, there would be 18 bacteria in the sample after 22 hours
