Profit per month

After prioritizing and making deals with eateries by their overall profits, Alice wants to track Delivr profits per month to see how well it's doing. You're here to help.

You're provided with two CTEs. The first stores revenue and the second stores cost. To access revenue and cost in one query, the two CTEs are joined in the last query. From there, you can apply the formula for profit Profit = Revenue - Cost to calculate profit per month.
