What is the equation for finding the revenue if you have a pizza selling for $15.00, total cost of $55.00 and labor is $4.00.

To find the revenue, you need to subtract the total cost, including labor, from the selling price of the pizza. The equation for finding the revenue is:

Revenue = Selling Price - Total Cost

In this case, the selling price of the pizza is $15.00, the total cost is $55.00, and the labor cost is $4.00.

Revenue = $15.00 - ($55.00 + $4.00)

To calculate this, you need to add the total cost of the pizza and the labor cost, and then subtract the sum from the selling price.

Revenue = $15.00 - $59.00

Finally, you subtract $59.00 from $15.00 to find the revenue.

Revenue = $-44.00

Therefore, the revenue in this case is -$44.00. However, a negative revenue indicates a loss rather than profit.
