Question

A colony of bacteria is growing exponentially according to the function below, where t is in hours. How many bacteria are there after 7 hours? Round to the nearest integer and do not include units in your answer.
B(t) = 4 * e^(0.8t)

Answer 1

t is in hours and the value of B(t) indicates the amount of the bacteria at a specific time t. So, all you have to do is solve for B(t) when t = 7.
