Mr. Creighton, the owner of the company is baffled that only a ten percent decline in sales has resulted in a twenty percent decline in profits. He asks you to explain to him how in spite of maintaining efficiency in operations by keeping variable expenses and contribution margin at the same percentage level, he has experienced a greater percentage decline in profits.
