Given:
Each part costs $7 to produce and distribute.
The total number of parts on selling is 300 to make the profit P.
To write the function expression in terms of sale price C and profit P:
As we know,
![\text{Profit}=\text{Selling price-cost price}](https://img.qammunity.org/2023/formulas/mathematics/college/820sftrrn36vblzvii32dppglsqf36r66i.png)
So, if we produce 1 part and sell that part, then the profit is
![P=C-7](https://img.qammunity.org/2023/formulas/mathematics/college/jua0gtudme1r6sx4iztuzgcwgbtuo5z18c.png)
For 300 parts, the profit is
![\begin{gathered} P=300(C-7) \\ P=300C-2100 \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/4sfc1san1upa9v7mfe0mcwhib98rqbc3c9.png)
Hence, the function is expressed in terms of P and C is,
![P=300C-2100](https://img.qammunity.org/2023/formulas/mathematics/college/27oqpc7yv0aauze0hdtosl2du9q6zng39p.png)
