Answer:

  • 15 pounds of cashews
  • 22 pounds of Brazil nuts

Step-by-step explanation:

Let c represent the weight of cashews in the mix. Then 37-c is the weight of Brazil nuts. The cost of the mix is ...

  7.40c +4.30(37 -c) = 5.56(37)

  3.10c +159.10 = 205.72 . . . . . simplify

  3.10c = 46.62 . . . . . . . . . . . . . subtract 159.10

  c = 15.0387 ≈ 15

15 pounds of cashews and 22 pounds of Brazil nuts should be used to make the mix.
