The quantity, q, of a certain skateboard sold depends on the selling price, p, in dollars, so we write q = f(p). You are given that f(115) = 15400 and f'(115) = -70. (a) What does f(115) = 15400 tell you about the sales of skateboards? When the price of the skateboard is $ , then skateboards will be sold. (b) What does f'(115) = -70 tell you about the sales of skateboards? If the price increases from $115 to $116, the number of skateboards sold would ---Select---by roughly (c) If the total revenue, R, earned by the sale of skateboards can be expressed as R = pq, find R '(p). OR'(p) = q OR'(p) = p + q OR'(p) = f'(p) + f(p) OR'(p) = pf '(p) + f(p) OR'(p) = p'q (d) If the skateboards are currently selling for $115, what happens to the revenue if the price is increased to $116? The revenue ---Select--- by roughly $ skateboards.

The quantity, q, of a certain skateboard sold depends on the selling price, p, in dollars, so we write q = f(p). You are given that f(115) = 15400 and f'(115) = -70. (a) What does f(115) = 15400 tell you about the sales of skateboards? When the price of the skateboard is $ then 1 skateboards will be sold. (b) What does f'(115) = -70 tell you about the sales of skateboards? If the price increases from $115 to $116, the number of skateboards sold would ---Select--- by roughly R'(p) = p + q OR'(p) = f'(p) + f(p) OR '(p) = pf '(p) + f(p) OR'(p) = p'q (c) If the total revenue, R, earned by the sale of skateboards can be expressed as R = pq, find R '(p). R'(p) = q (d) If the skateboards are currently selling for $115, what happens to the revenue if the price is increased to $116? The revenue ---Select--- by roughly $ skateboards.
