Transcribed Image Text:33 White & Becker Tools (W&B) requires 2,000 elec-
tric motors next month for its product line of weed
trimmers. Each motor is composed of three com-
ponents: a coil, a shaft, and housing. W&B has the
capability to produce these components or purchase
them from an outside vendor. The costs of produc-
ing them and purchasing them are shown in the
following table.

The components that are produced by W&B
must pass through three departments: fabrication,
molding, and inspection. The number of hours each
component requires in each department and the
total number of hours available next month in each
department are shown in the following table:

In order to determine the number of components
that will be produced and the number that will be
purchased, W&B has set the following goals, in
rank order:
Rank 1: The total costs to produce and purchase
components next month should not exceed
$14,000.
Rank 2: Idle time in the fabrication department
should be minimized.
Rank 3: At least 200 coils should be purchased from
the vendor next month.
Determine the number of components produced and
purchased next month, according to these ranked
goals.
