a.P
b.P'
c.Either P or P'. It is necessary to know whether the externality is positive or negative to

10) Scenario 13-10
Jessica makes photo frames. She spends $5 on the materials for each photo frame. She
can create one photo frame in an hour. She earns $10 per hour at a part-time job at the

11) A firm is currently producing 100 units of output per day. The manager reports to

profits (or minimize its losses).

a.market demand curve.
b.market supply curve.
c.equilibrium curve.
d.surplus or shortage depending on market conditions.
