Each parcel of land in a new development is selling for $15,000 and the total project revenue is estimated to be $5,000,000. The project lender has stated that the loan should be paid off when 80% of the total project revenue has been earned. The total loan amount is $3,500,000. What is the release price for each parcel?(The answer is $13,215) I can't figure out how the answer was found.
