GGC expects to spend $1.5 million on advertising this coming year and expects BLG to spend $1.2 million on advertising. The average household disposable income is $55,000 in the western suburbs and $25,000 in the eastern suburbs. GGC does not expect BLG to change its price from last year, since it has already distributed its glossy brochures (with the $2,100 price stated) in both suburbs, and its TV commercial has already been produced. GGC?s cost structure has been estimated as TVC = 755.363Q + 0.005where Q represents single lawn watering systems.a.Derive the demand curves for GGC?s product in each market.b.Plot graphically the demand and MR curves for each market, and also show GGC?s combined marginal revenue curve (?MR) and its MC curve.
