Constrained Optimization: Multiple Internal Constraints Fisher Company produces two types of components for airplanes: A and B, with unit contribution margins of $400 and $600, respectively. The components pass through three sequential processes: cutting, welding, and assembly. Data pertaining to these processes and market demand are given below (weekly data) Resource Cutting Welding Assembly Market demand (A) 50 Market demand () 40 Required: 1.
