1. Using a scale of 2 cm to represent 10 vans on the x-axis and 2 cm to represent 10 cars on the y-axis, draw the graphs of the lines associated with the inequalities; x+y ≤ 60, 10 ≤ y ≤ 60, y ≤ 2x. (I) Identify by shading, the region which satisfies all three inequalities mentioned above. The parking fee for a van is $6 and for a car is $5. (II) Write an expression in x and y for the total fees charged for parking x vans and y cars. (III) Using your graph, write down the coordinates of the vertices of the shaded region
