The number of seats at hard rock stadium is fixed at 70,000. Suppose the team raises the price of a ticket from $30, at which 70,000 are sold, to $40, and it sells 60,000 tickets. The price change would cause a change in consumer surplus of?

The correct answer is "(B) -$700,000; $0; $0".

Step-by-step explanation:

The tax caused a change in the consumer surplus of $-700000, a change in the producer surplus of $0, and a deadweight loss of $0.

The change in consumer surplus is due to the $ 10 increase lost by consumers (10 x 70000 = 70000).

The rest does not vary because management decided to raise the price of the product, instead of bearing the tax.

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,
