Homework Help: Math 116

Posted by KiKi on Sunday, March 21, 2010 at 11:23pm.

As you are leaving the community, you notice another new community just down the street. Because you are in the area, you decide to inquire about it.

a) The sales representative here tells you they also have two floor plans available, but they only have 30 homes available. Write an equation that illustrates the situation. Use x and y to denote floor plan #1 and floor plan #2 respectively.

b) The representative tells you that floor plan #1 sells for $229,900 and floor plan #2 sells for $399,000. She also mentions that all the available houses combined are worth $9,602,600. Write an equation that illustrates this situation. Use the same variables you used in part a.

c) Use elimination to determine how many houses with each floor plan are available. Show all detail calculations

Can someone help me get started on this I am so confused....

Thanks

I thought this question sounded vaguely familiar

Looks like the teacher simply changed the numbers since November
