Which of the following would most likely result in a decrease in the equilibrium price of oranges?

The diagram above shows the demand curve for a good. If the price increases from P1 to P2, and quantity consumed decreases from Q2 to Q1, consumer surplus decreases by the area

The tax (incidence) share paid by consumers of good X would be relatively higher than that paid by consumers of good Y.

Promoters of a rock group know that if they charged $80 a ticket, 4,000 people would buy tickets for a concert, and if they charged $40 a ticket, 8,000 people would buy tickets.
