In the summer of 1991, Sega launched a bundle of their Genesis video game console with Sonic the Hedgehog. To aggressively sell it, they lowered the price of the bundle from $190 to $150. Suppose marketing data showed that if the price was $190, they would have only sold 390,000 units that summer. Instead, at the new price, they sold 750,000 units that summer. What is the demand function, \(p(x)\), for the Genesis for that summer, where \(p\) is in dollars and \(x\) is the number of bundles sold?   TO DO: Change to “last week of June 1991” and divide all quantities by 10.
