In the lаst week оf June 1991, Segа lаunched a bundle оf their Genesis videо 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 39,000 units that week. Instead, at the new price, they sold 75,000 units that week. What is the demand function, (p(x)), for the Genesis for that week, where (p) is in dollars and (x) is the number of bundles sold?
