Please prepare the homework problems in the form of a Word and/or Excel file. Try to use one file to submit your answers, if possible, and include the questions with your answers. You must show your calculations.
Explain what is meant by cost behavior, and differentiate between the five general types of cost behavior (a minimum of 75 words).
Your nursing home defines output as a patient day. Its present volume is 26,000 patient days. The average cost per day is $90.00. Present revenues and costs are presented below:

Fixed-Price Patients (20,000 Patient Days) $1,800,000
Total Net Revenues $2,550,000
Costs
Amount

Fixed Costs $1,170,000
Variable Costs ($45/PD) $1,170,000

Net Income $210,000
Using this information, answer the following two questions:
What is the break-even in patient days for this nursing home, assuming no profit is required?
If volume goes up 10% to 28,600 patient days and payer mix is unchanged, what will net income be?
