I have a story problem
The representative tells you that floor plan #1 sells for $175,000 and floor plan #2 sells for $200,000.
----------------------------------
She also mentions that all the available houses combined are worth $7,200,000.
----------------------------------
Write an equation that eliminates the situation, using x an y as your variables. Then use elimination method to determine how many houses with each floor plan are available.
----
Let x be the # of 175000 homes
Let y be the # of 200000 homes
------------
Quantity Equation: x + y = 38
Value: 175000x + 200000y = 7,200,000
-----------------------------------------
Muliply thru the Quantity equation by 175000 to get:
175000x + 175000y = 38(175000)
-------------------------------
Subtract that from the Value equation and solve for "y":
25000y = 550000
y = 22 (# of $200,000 homes available)
----
Since x + y = 38, x = 38-22 = 16 (# of #175,000 homes available)
===========================
Comment: You have to post the total number of houses or
some other information relating the two floorplan
quantities.
