The management of Ditton Industries has determined that the daily marginal revenue function associated with selling x units of their deluxe toaster ovens is given by the following, where
R '(x) is measured in dollars/unit.
(a) Find the daily total revenue realized from the sale of 180 units of the toaster oven.
(b) Find the additional revenue realized when the production (and sales) level is increased from 180 to 280 units.
