Answer:
a. $1.25
Explanation:
From the image, we can determine the seller's position.
As the supply curve moves from [tex]S_{1}[/tex] to [tex]S_{2}[/tex], the sale will become fewer. As the government imposes a $2.25 tax on suppliers, the seller will receive less money despite getting more money for each sale from the customer.
Before imposing the tax, the seller received $2.50 for each sale. After imposing the ban, the supply curve shifts to the left, and the seller receive $3.50 before paying the tax. After paying the tax, the seller receives ($3.50 - 2.25) = $1.25.
