Answer: $25

Step-by-step explanation:

Total revenue, at price = $50

Total revenue = price × units sold

= $50 × 0

= 0

Total revenue, at price = $45

Total revenue = price × units sold

= $45 × 1

= $45

Total revenue, at price = $40

Total revenue = price × units sold

= $40 × 2

= $80

Total revenue, at price = $35

Total revenue = price × units sold

= $35 × 3

= $105

Marginal revenue of third unit =
(Change\ in\ total\ revenue)/(change\ in\ units\ sold)

=
(105 - 80)/(3 - 2)

= $25
