Acme's Marketing team has established a MSRP for each gadget based on the feedback of consumers and tech journalists that were selected to review the prototype gadgets. The MSRP has been set as $449, $499, and $425 for Gadgets A, B and C respectively. Acme's sales team wishes to establish a net price (to retailers) that will allow retailers a series of markdowns for the gadget, first by 15% during regular sale periods (to occur up to 3 times a year), with room for a second discount of 10% during special sale periods (Black Friday and Boxing Day), while still allowing the retailer a mark-up of at least 20% over the net price. Find the maximum net price for each gadget and determine how this net price impacts the breakeven analysis.
