Answer:
m/(1 - .8)
Step-by-step explanation:
She read 80% of her emails, which is .8 of the total. So her unread emails would be 100% - 80% = 1 - .8
that means me can be written as:
m = (1 - .8)t
where t is the total
If we solve for t, we get:
t = m/(1 - .8)
Answer with explanation:
Let number of emails in Danette inbox before she started Reading= x
Number of emails Read =80% of the email
Number of emails left after reading 80% of the emails =M
A.T.Q
[tex]\rightarrow x-\frac{80x}{100}=M\\\\\rightarrow \frac{100x-80x}{100}=M\\\\\rightarrow \frac{20x}{100}=M\\\\ \rightarrow x=\frac{100M}{20}\\\\x=5 M[/tex]
Number of emails in Danette inbox before she started Reading =5 M
