Question

Is this correct so far...I just want to know if I am doing this..





b) The representative tells you that floor plan #1 sells for $300,000 and floor plan #2 sells for $200,000. She also mentions that all the available houses combined are worth $3,300,000. Write an equation that illustrates this situation. Use the same variables you used in part a. (3 pts.)

300,000 + 200,000 =3300000


Multiply the first equation by 300,000
-300000x –300000 y = -5000000

Add to the second equation:
20000y = 500000
Divide by 20000:
y = 10

x +10 =
x =

of plan 1
of plan 2
