Math Problem Statement
When the admission price for a baseball game was $4 per ticket, 45,000 tickets were sold. When the price was raised to $5, only 40,000 tickets were sold. Assume that the demand function is linear and that the variable and fixed costs for the ball park owners are $0.10 and $95,000 respectively.
(a)
Find the profit P as a function of x, the number of tickets sold.
P(x) =
Solution
To find the profit as a function of , the number of tickets sold, we'll first determine the price per ticket as a function of , then calculate the revenue and costs, and finally determine the profit function.
Step 1: Determine the price function
Given the dataTo find the profit as a function of , the number of tickets sold, we'll first determine the price per ticket as a function of , then calculate the revenue and costs, and finally determine the profit function.
Step 1: Determine the price function
Given the
- When ,
- When ,
Assuming a linear demand function , we can find the slope using the two points:
Using the point-slope form of the line equation:
Simplifying, we find:
Step 2: Calculate Revenue and Costs
Revenue is the price per ticket multiplied by the number of tickets sold:
Total Costs consist of variable costs and fixed costs:
Step 3: Determine the Profit Function
Profit is given by the difference between revenue and total costs:
Simplifying the profit function:
