Answer:

702 emails

Step-by-step explanation:

This problem bothers on depreciation of value, in this context it is Joe's email that has depreciated by 10%.

Given data

Average personal emails received monthly = [tex]780 emails[/tex]

Average work emails received monthly[tex]= 760 emails[/tex]

     

      We are required to solve for the new amount of emails Joe will be receiving after changing his address, to find this value we need to solve for the depreciation of his personal mails.

      After solving for the depreciation , we then need to subtract the depreciation from the initial number of mails to get the new number of mails.

let us solve for 10% depreciation.

[tex]depreciation= \frac{10}{100} *780\\depreciation=0.1*780= 78 emails[/tex]

The new number of mails

[tex]= initial number of mail- depreciation\\ =780-78= 702 emails[/tex]

Joe will be receiving an average of 702 emails in his personal account monthly
