Walt needs the total mixture of walnuts in almost to be worth $3.92 per pound if walnuts cost $4.50 per pound and almonds cost $3.50 per pound how many pounds of each should use to make a50 lb mixture

Answer 1

4.5x + 3.5(50-x) = 3.92(50)

4.5x- 3.5x = 3.92(50) - 3.5(50)

x =0.42(50) = 21 pounds of $4.50 walnuts

50-x = 50-21 = 29 pounds of $3.50 almonds

4.5(21)+ 3.5(29) = 94.5 + 101.5 = 196 = 3.92(50)
