Refer to Figure 10-19. Note that the lines labeled “Demand” and “Social Value”are parallel.
Also, the slopes of

value decrease by $1.00 with each
additional unit of the good that is consumed, and (2) private
cost increases by $1.40 with each additional unit of the
good that is produced. Thus, when the

by
a. $28.00.
b. $31.40.
