Use Table 1 to evaluate all integrals involved in any solutions of Problems 71 − 94. 84. Average price. At a discount department store, the price–demand equation for premium motor oil is given by P = D ( x ) = 50 100 + 6 x where x is the number of cans of oil that can be sold at a price of $ p. Find the average price over the demand interval [50, 250].
