<PRE><B>Question 184934</B>
Elen wishes to mix candy worth 2.15/ pound with candy worth 3.92/ pound to produce 30 pounds of mixture worth 2.80/pound. How many pounds of the more expensive candy should he use?
-------------------------------
Value Equation:
value + value = value
2.15x + 3.92(30-x) = 2.80*30

Multiply thru by 100 to get:
215x + 392*30 - 392x = 280*30
-177x = -112*30
x = 18.98 lbs.(amt. of 2.15 candy)
30 - 18.98 = 11.02 lbs (amt. of 3.92 candy)
