Let c represent the number of pounds of cashews in the mix. The total cost of goods will be 8(35-c) + 15(c) = 14*35 (each product is (dollars/pound)*(pounds)) 8*35 - 8c + 15c = 14*35 (use the distributive property to eliminate parentheses) 7c = 6*35 (subtract 8*35 from both sides, collect terms) c = 6*5 (divide both sides by 7)

##### The mix should consist of 30 pounds of cashews and 5 pounds of trail mix.

These mixture problems tend to work out much more nicely if you let the variable represent the amount of the high-cost item.__Math Check__30*15 + 5*8 = 35*14 450 + 40 = 490 (yes)__Reasonableness Check__This makes a nice math problem, but this particular mixture is a bad idea from a business point of view. The mixture will be unattractive because of its heavy cashew content. The mixture will be less profitable because the cost of labor of making the mix is not reimbursed by any extra profit. As a practical matter, there should be more trail mix and fewer cashews.
