Believe it or not, but Mr. Wes' party hats for homeless cats shockingly fell through! His next venture is a sure bet though. He's going to sell lemonade outside of Wal-Mart and plans to open up a franchise outside of each store across America. The bank is playing hardball, and for his $1,500,000 loan, he will incur $600,000 worth of interest on a 10% interest rate! What is the length of the loan?
4 years
