Suppose you are in the market for a new home and are interested in a new housing community under construction in a different city. a) The sales representative informs you that there are two floor plans still available, and that there are a total of 56 houses available. Use x to represent floor plan #1 and y to represent floor plan #2. Write an equation that illustrates the situation. 56 =x + y b) The sales representative later indicates that there are 3 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. 3x=y Use the equations from part 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. If I swap the y in equation number 1 with 3x from equation number 2, I get 56= x + 3x 56 = 4x Floor plan number 1 would be x = 14 because 56 is divided by 4 (56/4). In floor plan #2 y =42
