The plant has an installation cost of $12 million, which will be depreciated straight-line to zero over its four- year life. If the plant has projected net income of $1,860,300, S1,913,600,S1,882,000, and $1,335,500 over these four years, what is the project's average accounting return (AAR)? (Do not round your intermediate calculations. Round the final answer to 2 decimal places. Omit % sign in your response.)
