Write an equation that illustrates the situation. b. The sales representative later indicates that there are three times as many homes available with the second floor plan than the first. Write an equation that illustrates this situation. Use the same variables you used in Part a. c. Use the equations from Parts a. and b. of this exercise as a system of equations. Use substitution to determine how many of each type of floor plan is available. Describe the steps you used to solve the problem. x + 3x = 56 4x = 56 x = 56/4 x = 14 houses with plan#1 and y = 3(14) y = 42 houses with plan#2 d. What are the intercepts of the equation from Part a. of this problem? What
