A manufacturer produces bolts of fabric with a fixed width. The quantity q of this fabric (measured in yards) that is sold is a function of the selling price p (in dollars per yard), so we can write
q = f(p).
Then the total revenue earned with selling price p is
R(p) = pf(p).
f(16) = 9000
f '(16) = −340,
R'(16) = ?

R(p) = pf(p)
Use derivative of product df(x)*g(x)/dx = df/dx * g(x) + f(x) * dg/dx
R'(p) = f(p) + p f'(p)
R'(16) = f(16) + 16*f'(16) = 9000 + 16 * (-340) = 3560.
