Answer:
1. Consumer Surplus
2. Neither
3. Neither
Step-by-step explanation:
Consumer Surplus is the difference between prevailing price & the maximum price consumers are willing to pay for a commodity
Producer Surplus is the difference between prevailing price & minimum price at which sellers are willing to sell a commodity
1. ' Even though I was willing to pay up to $191 for a used laptop, I bought a used laptop for only $185 ' : shows the difference between price paid by consumer (185) & maximum price consumer was willing to pay (191). So, it illustrates the case of Consumer Surplus.
2) & 3) don't illustrate case for any Surplus, as they have not arrived at a transaction price decision - based on supply & demand because of tax imposed by government.
