A company that sells sweatshirts finds that the profit can be modelled by P(s)= -0.30s^2+3.5s+11.15, where P(s) is the profit, in thousands of dollars, and s is the number of sweatshirts sold (expressed in thousands).
a) Calculate the average rate of change in profit for the following
intervals.
i) 1 ≤ s ≤ 2
ii) 2 ≤ s ≤ 3
iii) 3 ≤ s ≤ 4
iv) 4 ≤ s ≤ 5

b) As the number of sweatshirts sold increases, what do you notice
about the average rate of change in profit on each sweatshirt? What
does this mean?

c) Predict if the rate of change in profit will stay positive. Explain
what this means.
