Explanation: Consumer surplus is the total amount of benefit the consumers get when they buy a good at a price that is less than their willingness to pay for it.
Consumer surplus = Willingness to pay - Market price
When Felix buy the last cutter at the market price of $5, the CS is,
[tex]CS= $8 - $5 = $3[/tex]
When Tim buys the last cutter at the market price of $5, the CS is,
[tex]CS= $6 - $5 = $1[/tex]
Thus, the CS falls by $2.
