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

I have little understanding of what you did.
x*300,000+y*200,000=3,300,000 is the equation describing the words in the paragraph. You need one other equation to solve, for instance, x+y=somenumber
