Colonial Furniture, Ltd. is contemplating production of an office desk that would sell for $800. The production of each desk would require $310 in materials and 35 hours of labor at a cost of $8 per hour. Energy, supervisory, and other variable overhead costs would amount to $60 per unit. The accounting department has derived an allocated fixed overhead charge of $75 per desk (at a projected volume of 2000 units) to account for the expected increase in fixed costs.

B. Calculate the degree of operating leverage (DOL) at a projected volume of 2000 units and explain what the DOL means.
