After reading 80\%80% of her e-mails in her inbox, Danette still has MM unread e-mails.

NARA [144]

Answer: <em>The correct options are.....</em>

Step-by-step explanation:

Suppose, the number of e-mails Danette had in her inbox before she started reading was $X$ .

Percentage of read emails is 80%, so the number of read emails $= (\frac{80}{100}*X)=0.8X$

<u>Thus, the number of unread emails</u> $= X-0.8X=X(1-0.8)$ , <u>which is given as</u> $M$ .

So, the equation will be........

$X(1-0.8)=M\\ \\ \Rightarrow X=\frac{M}{1-0.8} (Answer: 1) \\ \\ \Rightarrow X=\frac{M}{0.2}\\ \\ \Rightarrow X=(\frac{1}{0.2})M=5M (Answer: 2)$

Thus, the expressions which could represent the number of e-mails Danette had in her inbox before she started reading are: $\frac{M}{1-0.8}$ or $5M$
