The average ticket price for a concert at the opera house was $50. The average attendance was 2500. When the ticket price was r

Ber [7]

Answer:

The price per ticket should be $37.5

Explanation:

First we need to determine the change in demand (attendance) as a result of every $1 increase in the price of ticket.

The ticket price increased by $4 (from 50 to 54) and the demand fell by 400 (from 2500 to 2100). The change per dollar is, 400 / 4 = 100.

So, for every $1 increase in price, demand falls by 100.

The revenue is calculated by multiplying price by quantity demanded. Revenue equation will be,

Let x be the change in price from $50.

Revenue = (50 + x) * (2500 - 100x)

Revenue = 125000 - 5000x + 2500x - 100x²

Revenue = 125000 - 2500x - 100x²

To calculate the price that maximizes the revenue, we need to take the derivative of this equation.

d/dx = 0 - 1 * 2500x° - 2 * 100x

0 = -2500 - 200x

2500 = -200x

2500 / -200 = x

-12.5 = x

Price should be 50 - 12.5 = 37.5

At price $37.5 the revenue of the Opera House is maximized.

garri49 [273]

Answer:

Missing out on the benefits I get from working out using exercise equipment in my garage.

Explanation:

When an option is chosen from alternatives, the opportunity cost is the "cost" incurred by not enjoying the benefit associated with the best alternative choice. The New Oxford American Dictionary defines it as "the loss of potential gain from other alternatives when one alternative is chosen." Since Choice B is the next best choice to hiking, missing out on the benefits of working out will be my opportunity cost.
