The daily goal of emails per day is required.

The goal of emails per day is 83.

The number of email addresses being collect is 74 per day.

This is 90% of the goal.

Let [tex]x[/tex] be the goal of emails per day

So,

[tex]90\%x=74\\\Rightarrow \dfrac{90}{100}x=74\\\Rightarrow x=\dfrac{74\times 100}{90}\\\Rightarrow x=82.2[/tex]

The goal of emails per day is 83.

The rounding is done to 83, since [tex]82\times 0.9=73.8<74[/tex]
