Question

A researcher is studying the growth of bacteria.

He starts with 60 of the bacteria. It grows

continuously at a rate of 4% per hour. How

many bacteria will there be in 17 hours?

(Round to the nearest integer if necessary)

Answer 1

101

Explanation:

We have to do 60 x .04 in order to find how much the bacteria grows per hour. 60 x 0.4 = 2.4

So, we know that the bacteria grows 2.4 more per hour

For 17 hours, we have to do 2.4 x 17 which is 100.8

We have to round it up to the nearest whole number which is 101
