Using a scale of 2cm 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. (a) Identify by shading, the region which satisfies all three inequalities. The parking fee for a van is $6 and for a car is $5. (b) Write an expression in x and y for the total fees charged for parking x vans and y cars
