A.Multiply the two demand curves together
B.Add their demand curves together
C.Subtract the demand of the person with the lower valuation of the public good from the demand of the person with the higher valuation of the public good
D.Subtract the demand of the person with the higher valuation of the public good from the demand of the person with the lower valuation of the public good
