Can I get help on the questions below?

20 800 Consider the above market demand function for a product. In which of the following scenarios will the producers' total revenue most likely increase following a price change? The price increases from $15 per unit to $16 per unit. The price decreases from $5 per unit to $4 per unit. The price increases from $9 per unit to $11 per unit. The price decreases from $17 per unit to $16 per unit.Citizen A Citizen B $22 $12 $20 $18 $10 58 Marginal Private Benefit Marginal Private Benefit $6 $4 $2 so 2 Number of Public Goods Number of Public Goods A country is populated with two citizens, Citizen A and Citizen B. The graph above shows the marginal private benefits they would enjoy from different units of a public good such as a fire station or a extra mile of a freeway. The marginal social cost of producing this public good is constant at MSC = $18. When the government asks these citizens to reveal their marginal private benefits for the good, they understate those benefits by 50 percent. For example, Citizen A will say that he will benefit only $9 from the first unit. Or Citizen B will say that she benefits only $3 from the second unit. In that case, how many units of this good will the government build? O 2 1 0 4
