Jose is making a trail mix. The recipe calls for 3 parts golden raisins to 2 parts cashews. Jose would like to make 30 cups of trail mix. How many cups of golden raisins and cashews does Jose need?

Answer provided by our tutors

Let

x = cups of golden raisins, x>=0

y = cups of cashews, y>=0

x : y = 3 : 2 cross multiply

2x = 3y

The total mix is 30 cups means:

x + y = 30

We have the following system of equations:

2x = 3y

x + y = 30
