    c. Current owners of the airline’s stock and potential buyers of the stock would adjust their
    estimates of what the value of the corporation’s stock should be. As a result, the supply curve
    for the stock would increase by k for each price, (note: k is the last 3 digit from your mobile
    number). The demand curve for the stock would totally change to be represent by this
    equation −
