Hello, dizizviet!

Here's the first one . . .

1) A baseball team is trying to determine what price to charge for tickets.

At a price of $10 per ticket, it averages 45,000 people per game.

For every increase of $1, it loses 5,000 people.

Everyone person at the game spends an average of $5 on concessions.

What price per ticket should be charged in order to maximize revenue?

Let = number of $1 increases in the price of ticket.

They will charge dollars per ticket.

For each , there are fewer ticket sales.

. . They will sell: . tickets.

So tickets are sold at dollars each.

The revenue from ticket sales is: . dollars.

The same ticketholders will spend $5 each on concessions.

The revenue from concessions is: . dollars.

Hence, the Total Revenue is: . dollars.

. . andis the function we must maximize.that
