Answer:

[tex]8.88*10^9\ cells[/tex]

Step-by-step explanation:

we know that

4% represent the percentage of cells labeled

so

96% represent the percentage of cells not labeled

Using proportion

Find out how many cells represent 96%

Let

x ----> the number of cells that represent 96%

[tex]\frac{3.7*10^8}{4}\frac{cells}{\%}=\frac{x}{96}\frac{cells}{\%}\\\\x=3.7*10^8(96)/4\\\\x=88.8*10^8\ cells\\\\x=8.88*10^9\ cells[/tex]
