Waterways mass-produces a special connector unit that it normally sells for $4.00. It sells approximately 38,100 of these units each year. The variable costs for each unit are $2.20. A company in Canada that has been unable to produce enough of a similar connector to meet customer demand would like to buy 14,700 of these units at $2.50 per unit. The production of these units is near full capacity at Waterways, so to accept the offer from the Canadian company would require temporarily adding another shift to its production line. To do this would increase variable manufacturing costs by $0.30 per unit. However, variable selling costs would be reduced by $0.20 a unit. An irrigation company has asked for a special order of 1,800 of the connectors. To meet this special order, Waterways would not need an additional shift, and the irrigation company is willing to pay $3.10 per unit. What are the consequences of Waterways agreeing to provide the 15,000 units to the Canadian company? Would this be a wise "special order" to accept?
