Dunkin Donuts has had a lot of success with its no-fun donut, but that product will be challenged by a new spinach donut that is also fat-free. Dunkin currently sells 58,386 no-fun donuts per year, and expects to sell 35,286 spinach donuts per year. However, Dunkin recognizes that 7,791 of those spinach donut sales would have been no-fun donuts, if the new product had not been launched. Calculate cannibalization rate for the new spinach donut. Report 25.5%, for example, as "25.5". Rounding: tenth of a percent.

MARKETING METRICS IS THE SUBJECT OF THE QUESTION.
