I want the answer as a text not by hand.

Data for speed Compagny for a recent month appear below:

Costs:

Ingredients 7800$

Miscellaneous supplies (Napkins, etc) 1200$

Rent 1000$

Wages for part time employees 3000$

Cart attendant salary 5000$

Total Costs 18000$

Part time employees are scheduled for busy times, but are sent home as soon as volumes drop enough to warrant it.

Number of units produced = 20,000 units

1. Categorize each cost as fixed or variable
2. Create a cost function.
