Answer

Explanation:

Step1: Find profit expression

Profit = Revenue - Cost. Revenue is $2x^{2}+17x - 175$ and cost is $2x^{2}-3x - 125$. So, Profit=$(2x^{2}+17x - 175)-(2x^{2}-3x - 125)$. [ \begin{align*} &(2x^{2}+17x - 175)-(2x^{2}-3x - 125)\ =&2x^{2}+17x - 175 - 2x^{2}+3x + 125\ =&(2x^{2}-2x^{2})+(17x + 3x)+(-175 + 125)\ =&20x-50 \end{align*} ]

Step2: Calculate profit for $x = 75$

Substitute $x = 75$ into the profit - expression $20x-50$. $20\times75-50=1500 - 50=1450$

Answer:

20x - 50; $1,450
