Kansas Instruments manufactures two models of pocket calculators. Per unit of the Basic model sells for $5.50, has direct material cost of $1.25 and requires 0.25 hours of labour to produce. Each calculator of the Scientist model sells for $7.50, has direct material cost of $1.63 and takes 0.375 hours to produce.

Each labour hour costs Kansas Instruments $6 and labour is currently very scarce, even though the demand for the companys calculators is very high. The company is currently producing 8,000 Basic calculators and 4,000 Scientist calculators each month. Fixed costs per month amount to $24,000.

Kansas Instruments has received a request from an overseas potential customer to manufacture a batch of calculators made to specific requirements. The overseas customer is offering the company a contract worth $35,000 for this order. The production manager has estimated the following facts with respect to this special order:

The labour time required for this contract would be 1,200 hours. The material cost would be $9,000 (excluding the cost of a special component not normally used by the company for manufacturing its regular calculators). The special components could either be purchased from a supplier for $2,500 or produced internally using materials that would cost $1,000 and additional labour time of 150 hours.

Required:

Advise the management of Kansas Instruments on the appropriate course of action.
