The representative tells you that floor plan #1 sells for $225,000 and floor plan #2 sells for $300,000. She also mentions that all the available houses combined are worth $10,350,000. Write an equation that illustrates this situation. Explain. Use the same variables you used in part a.
Is this right?:
255,000x+300,000y=10,350,000

yes, correct.

I have to use the elimination method to solve this system of equations but, I just do not get it.
x+y=42
255,000x+300,000y=10,350,000
