The no. of (N items) of a product sold depends on the price ($p) of each product. The relationship can be expressed by: N(p)=√(8000-15p^2)

Question

The price of each product increased from $10 to$15 .Find the average rate of change of the number of the product sold with respect to the price

Answer 1

The average rate of change over an interval is simply the change in y divided by the change in x. We have:

(N(15) - N(10)) / (15 - 10) = (68.007 - 88.600) / 5 = -20.593
