Prаirie Steel Wоrks Ltd. mаnufаctures industrial brackets and has a nоrmal mоnthly production capacity of 50,000 units. The company is currently producing and selling 38,000 units per month at a selling price of $32 per unit. Unit cost information is as follows: direct materials $11, direct labour $7, variable manufacturing overhead $4, and variable selling costs $3. Fixed manufacturing costs total $420,000 per month and are allocated at $10.50 per unit based on normal capacity. A foreign distributor has approached Prairie Steel with a one-time special order for 9,000 units at a price of $24 per unit. This order would not incur any variable selling costs, and accepting it would not affect existing customers or pricing. What is the impact on monthly operating income if Prairie Steel accepts the special order?
