Yard tools manufactures lawnmowers, weed-trimmers, and chainsaws. its sales mix and unit contribution margin are as follows. sales mix unit contribution margin lawnmowers 20 % $30 weed-trimmers 50 % $20 chainsaws 30 % $40 yard tools has fixed costs of $4,200,000. compute the number of units of each product that yard tools must sell in order to break even under this product mix.

Suppose that two firms produce differentiated products and compete in prices. as in class, the two firms are located at two ends of a line one mile apart. consumers are evenly distributed along the line. the firms have identical marginal cost, $60. firm b produces a product with value $110 to consumers.firm a (located at 0 on the unit line) produces a higher quality product with value $120 to consumers. the cost of travel are directly related to the distance a consumer travels to purchase a good. if a consumerhas to travel a mile to purchase a good, the incur a cost of $20. if they have to travel x fraction of a mile, they incur a cost of $20x. (a) write down the expressions for how much a consumer at location d would value the products sold by firms a and b, if they set prices p_{a} and p_{b} ? (b) based on your expressions in (a), how much will be demanded from each firm if prices p_{a} and p_{b} are set? (c) what are the nash equilibrium prices?
