Question 217466: the modern grocery store has cashews that sell for 4$ a pound and peanuts that sell for $2.25 a pound. how much of each must albert mix to get 70 pounds of mixture he can sell for $3 a pound Answer by checkley77(12844) (Show Source):
You can put this solution on YOUR website! 4x+2.25(70-x)=3*70
4x+157.5-2.25x=210
4x-2.25=210-157.5
1.75x=52.5
x=52.5/1.75
x=30 pounds of cashews is used.
70-30=40 pounds of peanuts is used.
Proof:
4*30+2.25*40=210
120+90=210=210
