Suppose that a wholesaler expects that his monthly revenue, in dollars, for an electronic game will be

R(x) = 200x 0.14x²,

0 x 800

where x is the number of units sold. Find his marginal revenue and interpret it when the quantity sold is the following.

(a)

x = 700

$ Interpret the marginal revenue.

The sale of the 701st unit results in a loss of this amount.

\The sale of the 700th unit results in a loss of revenue of this amount.

This is the additional revenue from the 700th unit.

(b)

x = 800

$ Interpret the marginal revenue.

The sale of the 800th unit results in a loss of revenue of this amount

.This is the additional revenue from the 700th unit.

This is the additional revenue from the 801st unit
