Part 1: The Miami Company suffered major losses in a fire on October 23, 2007. In addition to
destroying several buildings, the blaze destroyed the company's work in process inventory for an

Problem 2 - Cost Estimation

Dave's "Golden Brown" Pancake Restaurant features sourdough pancakes made form a
strain of sourdough dating back to the Alaskan gold rush. To plan for the future, Dave needs to
figure out his cost behavior patterns. He has the following information about his operating costs
and the number of pancakes served:

Month Number of Pancakes Total Operating Costs
July 3,600 $2,360
August 3,900 $2,390
September 3,200 $2,320
October 3,300 $2,330
November 3,850 $2,385
December 3,620 $2,362

Required:

1. Use the high-low method to determine Dave's operating cost equation.

2. Predict the total monthly operating costs if Dave serves $4,000 pancakes one
month.
