Answer: The slope of this profit curve is m = 1.05;
Paul profit is increasing at a rate of 1.05 dollar per bottle. Explanation :
• The standard linear function takes the form of y = mx +c
• Since the Pauls profit is given by the formula ,P = 1.05b -151,, The curve of this profit is in line with the slope ,m = 1.05, as comparing with the standard linear fuction.
,
• Therefore, Paul profit is increasing at a rate of 1.05 dollar per bottle.,
