Accessible description: The figure shows a linear demand curve for movies, where price is on the y-axis (dollars per movie) and quantity is on the x-axis (movies rented per hour). The line slopes downward starting at the point (0, 5). Other points along the demand curve include (1, 4.5), (2, 4), (3, 3.5), (4,3), (5, 2.5), (6, 2), (7, 1.5), (8, 1) (9,0.5) and (10, 0). f1q55g1.jpg The above figure shows the demand curve for movie rentals from Blockbuster. If Blockbuster lowered its price from $4.00 to $3.50, which of the following would happen?
