Pricing Strategy

A manufacturer of microwaves has discovered that male shoppers have little value for microwaves and attribute almost no extra value to an auto-defrost feature. Female shoppers generally value microwaves more than men and attribute greater value to the auto-defrost feature. There is little additional cost to incorporating an auto-defrost feature. Since men and women cannot be charged different prices for the same product, the manufacturer is considering introducing two different models. The manufacturer has determined that men value a simple microwave at $70 and one with auto-defrost at $80 while women value a simple microwave at $80 and one with auto-defrost at $150.
If there is an equal number of men and women, what pricing strategy will yield the greatest revenue? What if women compromise the bulk of microwave shoppers?
