Kingbird Inc. has been producing basketballs, volleyballs, soccer balls, and footballs for many years. Its manager, Jake, just came up with the idea to sell products in a bundle to provide more options for buyers. Jakes suggestion is to sell a bundle of balls (one of each of the four types listed, above) for $51. This represents a savings to the consumer of 15% off regular, individual prices for the items. The company has been operating within its target cost for all of these products, which have a combined total of $33 per bundle. The proposal includes a target sales volume of 10,000 bundles.

(Part C) If Kingbird finds that it has to drop its target selling price to $51.00 to really promote this bundle, what ROI will the company earn, incorporating the new target cost per unit from part (b)? (Round answer to 2 decimal places, e.g. 15.25%.)
