If a food product contains 10,000,000 microbes per gram and has a 99.99% kill rate, how many microbes per gram will survive?

In this scenario, you start with a total of 10,000,000 microbes per gram in the food product. A kill rate of 99.99% means that 99.99% of the microbes are destroyed, leaving only a small percentage alive.

To determine how many microbes survive, you first calculate the percentage that remains after the kill rate is applied. Since 99.99% of the microbes are killed, this means that only 0.01% survive.

To find the number of surviving microbes, multiply the initial amount (10,000,000) by the surviving percentage (0.01%). This calculation looks like this:

Surviving microbes = Total microbes x (Survival rate)

= 10,000,000 x 0.0001

= 1,000

This result indicates that after the kill process, 1,000 microbes per gram will survive. Thus, the calculation demonstrates how significantly effective a 99.99% kill rate is, leaving only a minimal amount of microbes per gram.
