Chapter 17, Problem 17.66P

Interpretation Introduction

Interpretation:

The U.S Public Health Service requires that milk fresh from a pasteurizer contains not more than $\text{20000}$ bacteria per milliliter.  It has been reported that number of bacteria in milk stored in a refrigerator at ${\text{4}}^{\text{°}}\text{C}\left({\text{40}}^{\text{°}}\text{F}\right)$ may double in $\text{39}\text{hours}$.  If a milk sample had $\text{20000}$ bacteria per milliliter after pasteurization, the bacteria count after ten days at this temperature has to be calculated.
