Answer:
<u>The correct answer is D. 53x - 12</u>
Step-by-step explanation:
Let's find P(x), this way:
Profits = Revenue - Cost
Profit function = Revenue function - Cost function
P (x) = R (x) - C (x)
Replacing with the real values we have:
P (x) = 60x - (12 + 7x)
P (x) = 60x - 12 - 7x
P (x) = 53x - 12
<u>The correct answer is D. 53x - 12</u>
