(Dollars per disk) | (Millions of disks) | (Millions of disks) |
11 | 1 | 15 |
10 | 2 | 12 |
9 | 4 | 9 |
8 | 6 | 6 |
7 | 8 | 3 |
6 | 10 | 1 |
Complete the first row of the following table by indicating the equilibrium price and the equilibrium quantity of flying disks in the absence of any price controls.
