Brown and Whin Ltd. (BWL) manufactures a wide range of automobile parts. BWL components are also found in many specialised gear applications such as: motors and agricultural equipment.

BWL’s annual requirement for these components is 7,000 units of T1 and 10,000 units of T2. Recently, in an attempt to minimise costs, management decided to devote additional machine time to other product lines, leaving only 42,000 machine hours per year for producing components T1 and T2. An outside company has offered to sell BWL its annual requirement of these components at prices of $62.00 for T1 and $79.00 for T2.
