The supply curve has a steep positive slope, and the demand curve has a negative slope. The curves intersect at 300 calculators, 30 dollars. A horizontal line, labeled world price with tariff, starts at 20 dollars on price of calculators and intersects the supply curve at 200 calculators and the demand curve at 500 calculators. A horizontal line, labeled world price, starts at 5 dollars on price of calculators and intersects the supply curve at 50 calculators and the demand curve at 800 calculators. After the $15 tariff is imposed, consumer surplus is: $3,000. $10,000. $2,000. $6,250
