Question 118089
How many pounds of Hamburger that cost $1.10 per pound must be mixed with 50 punds of hamburger that cost $1.80 per pound to make a mixture that cost $1.30 per pound?
------------
1.10 burger DATA:
Amount = x lbs ; value = 1.10x dollars
----------------
1.80 burger DATA:
Amount = 50 lbs; value = 1.80*50 = 90 dollars
------------------
Mixture burger DATA:
Amount = (x+50) lbs; Value = 1.3(x+50) = 1.3x + 65 dollars
---------------------
EQUATION:
value + value = value
1.10x + 90 = 1.3x+65
-0.2x = -25
x = 12.5 lbs (amount of 1.10 burger must be added to the mix)
