A trail mix company makes two mixes containing cashews and peanuts. The first mix (Mix 1) uses 3 units of cashews and 9 units of peanuts, while the second mix (Mix 2) uses 2 units of cashews and 6 units of peanuts. Suppose the company has 40 units of cashews and 120 units of peanuts available. A) If x is the quantity of Mix 1 they can produce and y is the quantity of Mix 2 they can produce, set up the linear system formed by each material. B) Solve the system for how many Mix 1 and Mix 2 they should produce to use all their inventory (nothing left over). Clearly list each possible integer solution
