Practice makes perfect
To find the average number of items sold, we will need to use our formula taking the arithmetic mean. The exercise provides the sum, so it is up to us to divide by the number of days in 5 years. Let's compute the number of days using the standard 365 days per year.
365 days/year * 5 years = 1825 days
Now that we know the number of days, we can find the average A sales per day dividing the total by 1825.
