1a) An appliance manufacturer produces two models of microwave ovens: the super nuker and the Micro-1000. Both models require fabrication and assembly work. The super nuker requires 4 hours of fabrication and 2 hours of assembly. The Micro-1000 requires 2 hours of manufacturing and 6 hours of assembly. There are 800 fabrication hours and 620 hours for assembly available this week. Each super nuker contributes $45 to profit and each Micro-1000 contributes $37 to profit. What quantities of super nukers and Micro-1000's will maximize profit? How much profit will the manufacturer realize?
