<PRE><B>Question 150534</B>
How many pounds of hamburger that costs $1.60 per pound must be mixed with 70 pounds of hamburger that costs $2.10 per pound to make a mixture that costs $1.70 per pound?
---------------------
Value Equation: 160x + 210*70 = 170(x+70)
160x + 210*70 = 170x + 170*70
10x = 40*70
x = 280 lbs. (Amt of 1.60 hamburger that must be added)
=====================
Cheers,
