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)
