When Joseph moved into a new house he plated two trees in his backyard. At the time of planting. Tree A was 16 inches tall and tree was 37 inches tall. Each year A thereafter, tree A grew by 6 inches per year and tree B grew by 3 inches per year. Let A represent the height of tree A t years after being planted and let B represent the heights of tree B t years after being planted. Write an equation for each situation, in terms of t, and determine the interval of time, t, when tree A is taller than tree B
