Since January 2010, a grape farmer has been growing red and green grapes. The number of red grape vines can be modeled by the function f(x) = 1,000(1.03)x, where x is the number of years since January 2010. The number of green grape vines can be modeled by the function g(x) = 20x + 1,125, where x is the number of years since January 2010. In what year will the number of each type of grape vine be approximately equal?
