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.

Suppose the Going Home Club held a fundraiser so they can… go home. They sold cookies for $2 each and brownies for $4 each. At the end of the day, the club leader tells everyone that they raised $4000, and they sold three times as many cookies as they did brownies. Set up (but do not solve) a system of equations to determine the numbers of cookies (\(c\)) and brownies (\(b\)) sold.
