Rather than pay six salespeople an average salary of $36,000 each, management has proposed that the salespeople receive a $10,000 base salary and a 9% commission based on gross sales. 1) Would the company have been better off financially if the new plan had been adopted for the year just ended? By how much? 2) What effect might paying a commission have on gross sales? Briefly explain. d In addition to the compensation plan described in part (c), Quebec is studying the impact of other operating changes as well. State whether you agree or disagree with the following findings of a newly hired staff accountant: e 1) A rise in property taxes will increase the break-even point. f 2) A decrease in raw material cost will increase the contribution margin and decrease total fixed costs.
