You're trying to determine whether or not to expand your business by building a new manufacturing plant. The plant has an installation cost of $10.8 million, which will be depreciated straightline to zero over its four-year life. If the plant has projected net income of $1,293,000,$1,725,000,$1,548,000, and $1,130,000 over these four years, what is the project's average accounting return (AAR)? (Do not round intermediate calculations and enter your answer as a percent rounded to 2 decimal places, e.g., 32.16.)
