An appliance manufacturer produces two models of microwave ovens: H and W. Both models require fabrication and assembly work; each H uses ten hours of fabrication and five hours of assembly, and each W uses two hours of fabrication and six hours of assembly. There are 550 fabrication hours available this week and 750 hours of assembly. Each H contributes $60 to profits, and each W contributes $44 to profits. What quantities of H and W will maximize profits?
