Worley Fluid Supplies produces three types of fluid handling equipment: control valves, metering pumps, and hydraulic cylinders. All three products require assembly and testing before they can be shipped to customers. The accompanying data provide the number of minutes that each type requires in assembly and testing, the profit, and sales estimates. A total of 3,000 minutes of assembly time and 2,100 minutes of testing time are available next week. Develop and solve a linear optimization model to determine how many pieces of equipment the company should make next week to maximize profit contribution.
