Final answer:
Colton's profit function is P(x) = -200 + 35x. After selling 3 paintings, his profit is calculated by substituting x with 3, resulting in P(3) = -95 dollars.
Step-by-step explanation:
The student question pertains to the profit function P(x) for Colton, an artist, which is given by P(x) = -200 + 35x. To calculate Colton's profit after selling 3 paintings, we substitute x with 3 in the profit function.
Using the profit function, the calculation would be as follows:
- Substitute x with 3: P(3) = -200 + 35(3).
- Multiply 35 by 3: P(3) = -200 + 105.
- Add -200 and 105: P(3) = -95.
Therefore, Colton's profit after selling 3 paintings would be -95 dollars.
