Question 233472: a store sells mixtures of peanuts and almonds for 4.50lb,peanuts sell for 2.95per pound almonds sell for 5.95 per pound how many pounds of each should be used to make 90 pounds of this mixture Answer by checkley77(12844) (Show Source):
You can put this solution on YOUR website! 5.95x+2.95(90-x)=4.50*90
5.95x+265.5-2.95x=405
3x=405-265.5
3x=139.5
x=139.5/3
x=46.5 lbs. of almonds is used.
90-46.5=43.5 lbs. of peanuts is used.
Proof:
5.95*46.5+2.95*43.5=4.50*90
276.675+128.325=405
405=405
