A biological us looks at 20 cell phone cell samples daily the biological it works and days looking at samples translate, the word into an algebraic expression is

Let's define the variable "x" as the number of days that the biologist works. Since the biologist looks at 20 cell phone cell samples daily, the total number of cell phone samples the biologist will look at in "x" days would be 20x.

Therefore, the algebraic expression would be:

20x
