Suppose an airline is flying a 10-seat plane from washington d. c. to chicago. suppose tickets on the flight cost $300 and passengers who buy tickets fail to show up for their flight 10% of the time. if a passenger doesn’t show up, they forfeit the cost of the ticket. the airline can overbook the flight, i. e., it can sell more than 10 tickets even though the plane only has 10 seats. however, if a passenger with a valid ticket arrives for the flight and cannot be seated, the airline will have to refund her $300 and pay compensation of $100. if the airline wants to maximize profits, how many tickets should it sell?

so firstly, we need to isolate the y variables to be able to solve these inequalities. firstly, add 0.5x on both sides of the first inequality and subtract 1.5x on both sides of the second inequality:

now since the slope is positive for the first inequality, this means that the line going upwards belongs to the first inequality, and the line going downwards belongs to the second inequality.

next, since y ≥ in the first inequality, this means that the shaded region will be above the first inequality's line, thus shading regions a and b.

next, since y ≤ in the second inequality, this means that the shaded region is going to be below this line, thus shading regions a and c.

since both lines shade region a, this means that region a is the solution.
