After reading 80% of her e-mails in her inbox, Danette still has M unread e-mails. Which of the following expressions could repr
sergey [27]

Answer:

(Choice A) 5M

Step-by-step explanation:

Let total no. of e-mails in inbox be x

Since she read 80 % of mails i.e 80 % of x

⇒80\% \times x

⇒\frac{80}{100}\times x

⇒0.8 x

So, she read 0.8x e-mails.

So, remaining email = total e-mails - read e-mails

                                  =x-0.8x

Since we are given that Danette still has M unread e-mails.

⇒ M=x-0.8x

⇒ M=x(1-0.8)

⇒ M=x\times 0.2

⇒ \frac{M}{0.2}=x

⇒ \frac{10M}{2}=x

⇒ 5M=x

Thus the expression  represent the number of e-mails Danette had in her inbox before she started reading is 5M.

Hence Choice A is correct.
