An automotive plant makes the Quartz and the Pacer. The plant can produce no more than 1500 cars per week, and they can make at most 800 Quartz cars and 900 Pacers each week. If the profit on a Quartz is $700 and the profit on a Pacer is $600, find how many of each type of car the plant should produce to maximize profit. Let x = number of Quartz cars produced Let y = number of Pacer cars produced
