RoverPlus, a pet product superstore, is considering pricing a new RoverPlus labeled dog food. The company will buy the premium dog food from a company in Indiana that packs the product with a RoverPlus label. Rover pays $6 for a 50-pound bag delivered to its store. The company also sells Royal Dog Food (under the Royal Dog Food label), which it purchases for $9 per 50-pound bag and sells for $16.99. The company currently sells 25,000 bags of Royal Dog Food per month, but that is expected to change when the RoverPlus brand is introduced. The company will continue to price the Royal Dog Food brand at $16.99. The quantity of RoverPlus and the quantity of Royal Dog Food that will be sold at various prices for Royal are estimated as: Price of RoverPlus Quantity RoverPlus Quantity Royal $8.99 35,000 11,000 $9.99 34,500 11,300 $10.99 34,000 11,500 $11.99 33,000 12,000 $12.99 30,000 13,000 $13.99 25,000 14,000 $14.99 15,000 15,000 $15.99 10,000 19,000 $16.99 5,000 21,000 For example, if RoverPlus is priced at $8.99, the company will sell 35,000 bags of RoverPlus and 11,000 bags of Royal at $16.99. On the other hand, if the company prices RoverPlus at $16.99, it will sell 5,000 bags of RoverPlus and 21,000 bags of Royal at $16.99. This is 4,000 fewer bags of Royal than is currently being sold. a.

At the price calculated in part a., what is the incremental profit over the profit earned before the introduction of the RoverPlus branded god food?
