21. Suppose that News Corp., which controls the United States' largest satellite-to-TV broadcaster, is contemplating launching a Spaceway satellite that could provide high-speed Internet service. Prior to launching the Spaceway satellite, suppose that News Corp. used least squares to estimate the regression line of demand for satellite Internet services. The best-fitting results indicate that demand is Qdsat = 152.5 - .8Psat + 1.2Pdsl + .5Pcable (in thousands) Where Psat is the price of satellite Internet service, Pdsl is the price of DSL Internet service, and Pcable is the price of high-speed cable Internet service. The price of DSL, Pdsl, is $25 per month and the monthly price of high-speed cable Internet, Pcable, is $50. Furthermore , News Corp. has identified that its monthly revenues need to be at least $15 million to cover its monthly costs. If News Corp. set its monthly subscription price for satellite Internet service at $55, would its revenue be sufficiently high to cover its cost? Is it possible for News Corp. to cover its cost give the current demand function? Justify your
