Answer 1

Answer:

  36 pounds of cashews

Step-by-step explanation:

Let c represent the pounds of cashews in the mix. Then 40-c will be the pounds of walnuts, and the cost of the mix will be ...

  1.58c +0.78(40-c) = 1.50(40)

  0.80c +31.20 = 60.00 . . . . eliminate parentheses

  0.80c = 28.80 . . . . . . . . . . .subtract 31.20

  c = 36 . . . . . . . . . . . . . . . . . .divide by 0.80

36 pounds of cashews must be mixed with 4 pounds of walnuts to make 40 pounds of mix.
