You can put this solution on YOUR website! how many kg of cashews at $6.00 per kg. must be added to 20 kg of peanuts at $3.25 per kg, to get
a mixture worth $4.50 per kg solve using linear equation
------------------
Let amt of cashews be "x" kg ; value is 6x dollars
----------------
Amt of peanuts is 20 kg; value is 20*3.25 = 65 dollars.
----------------
Amt of mixture is "x+20" kg ;value is 4.5(x+20) = 4.5x+90 dollars
-------------------
EQUATION:
value + value = value
6x + 65 = 4.5x+90
1.5x = 25
x = 16 2/3 kg (amt of cashews needed for the mixture)
