The person has at most 300000 to purchase the cars. At any given time there are at most 13 drivers available to operate the taxis. 1. Taking x as the number of medium-sized cars and y as the number of large cars, write down two inequalities in x andy and illustrate these inequalities on the graph. 2. The estimate of the monthly profit on a medium-sized car is 800 and on a large car is 900. How many of each type of car should the person buy to maximise profit? 3.
