the sales representative informs you that there are two floor plans available, and that there are a total of 56 available. use x to represent floor plan #1 and y to represent floor plan #2. write an equation.

the sales representative later indicates that there are 3 times as many houses availablr with the second floor bplan than the first . write an equation that illustrates this situation. use the same variables yyou used in part a.

use the equations from part a and b of this exercise as a system of equations. use substition to determine how many of each type of floor plan is available. describe the steps you used to solve the problem.

what are the intercepts of the equation from part of this proble? what are the intercepts from part b this problem? where would the lines intersect if you solved the system by graphing?

as you are leaving the community you notice another new community just down the street. because you are in the area you decide to inquire about it.

the sales representative here tells you they also have two floor plans available but they only have 38 homes available write an equation tha illustrates this situation. use x and y to denote floor plan #1 and floor plan #2 respectively.
