To solve the problem step by step:
### Part 1: Profit Function
The profit \( P(x) \) is calculated as the difference between total revenue \( R(x) \) and total cost \( C(x) \).
Given:
- Cost function: \( C(x) = 15x + 3611 \)
- Revenue function: \( R(x) = 82x \)
The profit function can be expressed as:
\[
P(x) = R(x) - C(x)
\]
Substituting in the given functions:
\[
P(x) = 82x - (15x + 3611)
\]
Simplifying this:
\[
P(x) = 82x - 15x - 3611
\]
\[
P(x) = 67x - 3611
\]
### Part 2: Profit for 150 Bicycles
To find the profit for \( x = 150 \):
\[
P(150) = 67(150) - 3611
\]
Calculating this:
\[
P(150) = 10050 - 3611 = 6439
\]
So, the profit is \( \$6439 \).
### Part 3: Average Profit per Bicycle Function
The average profit per bicycle, denoted as \( \overline{P}(x) \), is the total profit divided by the number of bicycles \( x \):
\[
\overline{P}(x) = \frac{P(x)}{x}
\]
Substituting the profit function we derived:
\[
\overline{P}(x) = \frac{67x - 3611}{x} = 67 - \frac{3611}{x}
\]
### Part 4: Average Profit per Bicycle for 150 Bicycles
To find the average profit per bicycle when \( x = 150 \):
\[
\overline{P}(150) = 67 - \frac{3611}{150}
\]
Calculating \( \frac{3611}{150} \):
\[
\frac{3611}{150} \approx 24.0733
\]
Therefore:
\[
\overline{P}(150) = 67 - 24.0733 \approx 42.9267
\]
Rounding to the nearest cent:
\[
\overline{P}(150) \approx 42.93
\]
### Final Summary:
- **Part 1:** \( P(x) = 67x - 3611 \)
- **Part 2:** The profit is \( \$6439 \)
- **Part 3:** \( \overline{P}(x) = 67 - \frac{3611}{x} \)
- **Part 4:** The average profit per bicycle is \( \$42.93 \) (rounded to the nearest cent).
### Part 1: Profit Function
The profit \( P(x) \) is calculated as the difference between total revenue \( R(x) \) and total cost \( C(x) \).
Given:
- Cost function: \( C(x) = 15x + 3611 \)
- Revenue function: \( R(x) = 82x \)
The profit function can be expressed as:
\[
P(x) = R(x) - C(x)
\]
Substituting in the given functions:
\[
P(x) = 82x - (15x + 3611)
\]
Simplifying this:
\[
P(x) = 82x - 15x - 3611
\]
\[
P(x) = 67x - 3611
\]
### Part 2: Profit for 150 Bicycles
To find the profit for \( x = 150 \):
\[
P(150) = 67(150) - 3611
\]
Calculating this:
\[
P(150) = 10050 - 3611 = 6439
\]
So, the profit is \( \$6439 \).
### Part 3: Average Profit per Bicycle Function
The average profit per bicycle, denoted as \( \overline{P}(x) \), is the total profit divided by the number of bicycles \( x \):
\[
\overline{P}(x) = \frac{P(x)}{x}
\]
Substituting the profit function we derived:
\[
\overline{P}(x) = \frac{67x - 3611}{x} = 67 - \frac{3611}{x}
\]
### Part 4: Average Profit per Bicycle for 150 Bicycles
To find the average profit per bicycle when \( x = 150 \):
\[
\overline{P}(150) = 67 - \frac{3611}{150}
\]
Calculating \( \frac{3611}{150} \):
\[
\frac{3611}{150} \approx 24.0733
\]
Therefore:
\[
\overline{P}(150) = 67 - 24.0733 \approx 42.9267
\]
Rounding to the nearest cent:
\[
\overline{P}(150) \approx 42.93
\]
### Final Summary:

- **Part 3:** \( \overline{P}(x) = 67 - \frac{3611}{x} \)
