a biologists looks 20 cell samples daily the biologist works n days looking at samples translate the words into an algebraic expression
Let's denote the number of days the biologist works as "n".
The number of cell samples the biologist looks at daily is given as 20.
Thus, the total number of cell samples the biologist looks at in "n" days can be expressed algebraically as:
20n
So, the algebraic expression would be 20n.
