Question

A school fund-raising group sells chocolate bars to help finance a swimming pool for
their physical education program. The group finds that when they set their price at x dollars
per bar (where 0 <xs 5), their total sales revenue (in dollars) is given by the function
R(x) = -500x² + 3000x.
(a) Evaluate R(2) and R(4). What do these values represent?
(b) Use a graphing calculator to draw a graph of R. What does the graph tell us about
what happens to revenue as the price increases from 0 to 5 dollars?
(c) What is the maximum revenue, and at what price is it achieved?

Scientists around the world have collected data revealing that there is a linear relation- ship between the length (snout-to-vent) of a snake and the length of the fish that they can eat. This relationship is given by l(x) = -3.6 +0.17x where x is the snout-to-vent length (cm) of the snake and 1(x) is the predicted length(cm) of the fish. (a) Use the function to estimate the size of fish that a snake whose snout-to-vent length is 70 cm, will choose for their prey. (b) Calculate l'(70) and interpret the results. 1. ints ints
