For a certain small town, the table shows the demand schedule for water. Assume the marginal cost of supplying water is constant at $4 per bottle. Price 2843545 1.800 2.200 3.600 4.400 $9 $8 $7 $6 $5 $4 $3 $2 Quantity (bottles) 100 200 300 400 500 600 700 800 Refer to Table 17-8. If there are two suppliers of water, Mort and Callie, then what will be their combined level of output when a Nash equilibrium is reached?
