Response:

Q = 435/22.5 = 19 streetlights

Clarification:

Given that the streetlights represent a public good

To derive the market demand curve, we sum them in a vertical manner

P = 20*20Q - 20*Q

P = 5*( - 5*Q/2

thus

P = 445 - 22.5Q

The social optimum quantity of streetlights

MB20 + MB5 = MC

400 - 20Q + 45 - 2.5Q = 10

22.5Q = 435

Q = 435/22.5 = 19 streetlights

Answer:

The total payoff is  $50000

Explanation:

solution

The payment is represented at a certain point in a circular format.

This reflects the cumulative results and their probabilities.

The total payoff point is

total payoff  = 0.5 × $100,000 + 0.5 × 0

total payoff  =  $50000

It indicates that the best decision would be the cancer lab, as it presents the highest expected return of 60000
