a) Substitute t = 2 into the formula
= 600e^0.1(2)
= 600e^0.2
= 732.84 million
Therefore, 732.84 million bacteria are present after 2 days
b) Substituting t = 4 days we get
= 600e^0.1(4)
= 600e0.4
= 895.09 million
Hence, 895.09 million bacteria are present after 4 days
c) 2 weeks = 14 days
Substituting t = 14 days we get
= 600e^0.1(14)
= 600e^0.4
= 2433.12 million
Thus, 2433.12 million bacteria are present after 2 weeks
