Answer:
$60
Step-by-step explanation:
Consumer surplus is the difference between the willingness to pay of a consumer and the price of the good.
Consumer surplus = willingness to pay – price of the good
Consumer surplus received by Patricia = $110 - $85 = $25
Consumer surplus received by Cecilia = $170 - $135 = $35
Sum of the surpluses = $25 + $35 = $60
