You can put this solution on YOUR website!
Let x= amount of granola
Then 25-x=amount of raisins
$4x+$2(25-x)=$80 simplifying, we get:
$4x+$50-$2x=$80 or
$4x-$2x=$80-$50
$2x=$30
x=15 lbs of granola
25-x=25-15=10 lbs of raisins
ck
4(15)+2(10)=80
60+20=80
80=80
Hope this helps. Happy holidays--ptaylor
