Outback Steakhouse has 930 restaurants offering steak, chicken, and seafood served in an Australian-themed atmosphere. Maintaining a clean environment for customers is a key success factor. Each restaurant is cleaned regularly after closing. In addition to regular cleaning from 5 to 20 times per month, depending on various factors including the amount of business, a special treatment is given to the floors consisting of breaking down the wax and rewaxing. So the total number of times a restaurant is cleaned varies between 35 to 50 times per month. The two most costly resources needed to clean an Outback restaurant are labor and supplies. The cost driver for both resources is square feet cleaned. Cleaning laborers are paid the same salary regardless of the number of times a restaurant is cleaned. Cleaning supplies used per square foot for regular and special cleaning are about the same. Suppose one of the local Outback restaurants in Tacoma has 4,000 square feet. In October, the restaurant was cleaned 35 times, at a total cost of $26,400. In November, the restaurant was cleaned 38 times for a total cost of $27,120. The month of December is typically much busier, so the restaurant manager expects to clean 50 times in December. Show vour calculations for each of the following questions 1. What is the total amount of fixed costs? 2. What is the variable cost per unit? 3. What would be the total costs if the restaurant was cleaned 50 times in December? Suppose Outback can hire an outside cleaning company to clean the restaurant as needed. The charge rate for cleaning is S.17 per square foot. If the outside cleaning company is hired, Outback can lay off the workers who are now cleaning and spend nothing on cleaning supplies. Will Outback save money with the outside cleaning company during December? 4. How many times would the Tacoma restaurant be cleaned for the manager to be indifferent as to using its own in-house cleaner's verses an outside cleaning company? (rounded to the next highest number)Hint: Set the in-house cost of cleaning equal to the outside cleaning cost at "x" times of cleaning. 5
