MARKETING METRICS IS THE ACTUAL SUBJECT!!!

Mimi's Muffins sells muffins with a variety of flavors and fillings. Their Banana Nut muffin is a favorite. Mimi's is thinking about adding a new Savory Stuffed muffin to the line-up, but worries about cannibalization. Mimi's expects to sell 6,670 units of its Banana Nut muffin this year, if the new muffin is not introduced. Mimi's expects the new Savory Stuffed muffin to sell 5,512 units if it introduced, but then expects sales of the Banana Nut muffin to fall to 3,119 units. Compute the cannibalization rate implied by these numbers. (Rounding: tenth of a percent. Report 45.2%, for example, as "45.2".)
