The demand curve for her product is given by p1 =122 - 2x1 in the 1st market also p2 = 306 - 5x2 in the second market, where xi is the quantity sold in market i also pi is the price charged in market i. She has a constant marginal cost of production, c = 6 also no fixed costs. She can charge different prices in the two markets.
