Question 286044: The sales representative here tells you they also have two floor plans available, but they only have 42 homes available. The representative tells you that floor plan #1 sells for $100,000 and floor plan #2 sells for $150,000. She also mentions that all the available houses combined are worth $6 million. Write a system of equations that illustrates this situation. Use x to represent floor plan #1 and y to represent floor plan #2.
( I think the equations would be x + 100,000 = 6,000,000 and y + 150,000 =6,000,000 But im second guessing myself.)
