The quantity, q, of a certain skateboard sold dependson the selling price, p, in dollars, so we writeq = f(p). You are given thatf(100) = 15200 and f '(100) = ?90.
(a) What does f(100) = 15200 tell you about the salesof skateboards?
When the price of the skateboard is $_________ , then ______skateboards will be sold.
What does f '(100) = ?90 tell you about the sales ofskateboards?
If the price increases from $100 to $101, the number ofskateboards sold would _______ (increase/decrease) byroughly________ skateboards
(b) The total revenue, R, earned by the sale ofskateboards is given by R = pq. Find R'(p).(chose)
-R '(p) = p 'q
-R '(p) = pf '(p) +f(p)
- R '(p) = p + q
-R '(p) = q
-R '(p) = f '(p) +f(p)
(c) If the skateboards are currently selling for $100, whathappens to revenue if the price is increased to $101?
The revenue ---Select--- (increases/decreases) byroughly $ _______.
