*Rounded

1. Using the high-low method of cost estimation, estimate the behavior of the maintenance costs incurred by Nations Capital Fitness, Inc. Express the cost behavior pattern in equation form. (Round coefficient of X to 2 decimal places and other answer to the nearest whole dollar amount.)

2. Using your answer to requirement 1, what is the variable component of the maintenance cost? (Round your answer to 2 decimal places.)

3. Compute the predicted maintenance cost at 630 hours of activity.

4-a. Compute the variable cost per hour and the fixed cost per hour at 640 hours of activity. (Round your answers to 2 decimal places.)

4-b. Why is the fixed cost per hour possibly misleading?
