1. Use this data to prepare cost formulas using a) the high-low method, and b) regression analysis. Show the cost formula from each calculation in the form:

Overhead = Fixed cost + MH*(Variable OH per unit)

2. Assume that InStay decides to use the cost formula from the regression analysis. Briefly explain in your own words how the company will make use of the formula.
