The manager of a bulk foods establishment sells a trail mix for $6 per pound and premium cashews for $12 per pound. The manager wishes to make 105 pound nut mixture that will sell for $10 per pound. How many pounds of peanuts should be used?

Respuesta :

Answer:

70

Explanation:

12X+6(105-X)=105*10

12X+630-6X=1050

6X=1050-630

6X=420

X=420/6

So,

  • X=70 LBS. OF $12 CASHEWS IS USED.
  • 105-70=35 LBS. OF $6 TRAIL MIX IS USED.

PROOF:

12*70+6*35=105*10

840+210=1050

1050=1050
