Question

I am stuck with this problem can some let me know how to work this problem please help me




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 = 10000

x =10000
y

of plan 1
of plan 2

Answer 1

300,000 + 200,000 =3300000 is an illogical and false statement.

did you mean 300,000x + 200,000y =3300000 ?
then simplify by dividing each term by 100 000
3x + 2y = 33

you have no other information I can use to form a second equation.

Answer 2

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 = 10000

x =10000
y =

of plan 1
of plan 2



thank you for your help..This the whole problem
