To keep things simple, suppose that Abby and Brad can pump as much water as they want without cost so that the marginal cost is zero. The weekly town demand schedule and total revenue schedule for water is shown in the table below: Quantity(in gallons) Price Total Revenue(and Total Profit) 0 $12 $0 1 $11 $11 2 $10 $20 3 $9 $27 4 $8 $32 5 $7 $35 6 $6 $36 7 $5 $35 8 $4 $32 9 $3 $27 10 $2 $20 11 $1 $11 12 $0 $0 Refer to Table 17-2.
