1.) Expenses for a Pizza restaurant include raw material for pizza at $6.00 per slice, $124.00 as monthly rental and $36.00 monthly as insurance. Lost sale expense is considered to be $5.00 per unhappy customer. Leftover Pizza can be sold for $3. The restaurant is open 25 days in a month.

Today the restaurant prepared 200.00 pizza slices and sells them for $10.00/slice. There was a party at a nearby office so the demand for pizza went up to 224.00 slices. How much profit did the restaurant earn today?

The answer is $614, but I have no idea how to derive that answer.
