*Avery has an average of 98.25 phones sold every 10 days.*

We want to find how many phones were sold in the month of April (30 days).

Since average is calculated by \({sum \over count}\)....

sum = x

count = 3

average = 98.25

\({x \over 3} = {98.25}\)

\(x = {294.75}\)

Is this right? I just wanted to make sure :) I'm pretty sure you can't sell a 294.75 number of phones so I'm confused?

Your answer is correct because you are given a fraction of a phone in "98.25 phones sold in 10 days".

Now, I would solve it this way:

98.25 phones / 10 days =9.825 phones sold in 1 day.

9.825 phones x 30 days(in April) =294.75, which is what you got. Since you can't have a fraction of a phone, then you simply round it up, in this case, to: 295 phones sold in April.
