Fоr Questiоn 5, yоu need to cаlculаte the Averаge sales per unit by region for 2024. The Average sales per unit would be the ratio between the total sales and the total units. We have calculated the total sales in previous questions. For total units, you need to sum the units_sold. The output of the query should show region and average sales per unit rounded to 2 decimal places, sorted in ascending order of average sales per unit. If you're not sure how to put the query together, follow the steps below, otherwise jump to the question in the last line: 1) Which tables do you need to join and by what columns (HINT: This will require a 4 table join)? Make sure you have the correct join. To get the Average sales per unit, you need to divide ( use the forward slash (/)) the sum of price per unit *units sold by the sum of units_sold. If you output the average sales per unit across the datasets, you should get a value 131.88 2) To limit the data for 2024, you will need to use the YEAR() function on invoice date, in the appropriate clause. Use GROUP BY on the region and. Use the alias 'average_sales_per_unit' for the aggregated column. Sort the output by ascending order of the average_sales_per_unit. 3) Use the ROUND() function on the calculation for the average_sales_per_unit to round to 2 decimal places. The output will look similar to this (Values are fake though) : Question: Write a query to get the average sales per unit by region, rounded to 2 decimals. Sort the output in ascending order of average sales per unit. What region had the lowest average sales per unit? What was the average sales per unit for that region?
