The marginal revenue function on sales of q units of a product is r'(q)=240-18√q dollars per unit.

estimate the total revenue if sales are 100 units.
what is the marginal revenue at 100 units?
estimate the total revenue if sales are 101 units.

Total revenue R(q) = ∫R'(q) dq = ∫(240 - 18√q)dq = 240q - 12q^3/2
R(100) = 240(100) - 12(100)^3/2 = 24000 - 12(1000) = $12,000

Marginal revenue at 100 units R'(100) = 240 - 18√100 = 240 - 18(10) = $60

Revenue at 101 units = R(101) = 240(101) - 12(101)^3/2 = 24,240 - 12,180 = $12,060
