In the past, Maxwell's Coffee and Cakes competitor, Sammy's Best Cakes sold 10,000 mini cakes for $5 each. This year, Sammy's Best Cakes has made some new investments that she thinks will increase demand for her mini cakes. However, to cover her investments, she will now charge $7.10 for the first 6,595 cakes, $11.14 for the second 7,182 cakes and $14.31 for the last 6,043. Each cake costs $4.63 to produce.

 Assuming she meets her demand target, what will be her average revenue? Round to the nearest two decimals (0.00).
