Answer:
d. A tax of $18,000
Step-by-step explanation:
If the price is higher than $525,000 which is his reservation price, the buyer will not buy the good
(1+t) > $525,000 / $510,000
1+t > 1.03
t > 0.03
t > 3%
3% of $510,000 = $15,300. So if the tax is greater than $15,300, the buyer will not buy the good . Hence, the answer is option (D) A tax of $18,000 as this tax is higher than $15,300 while other option are less than $15,300
