The initial expression is:

So we can solve for r so:
Answer:
16 cups of cashews
12 cups of almonds
Step-by-step explanation:
Let's say x is the cups of cashews and y is the cups of almonds.
We can write two equations:
x / y = (1/3) / (1/4) = 4/3
x + y = 28
Solve the system of equations using substitution.
x = 4/3 y
4/3 y + y = 28
7/3 y = 28
y = 12
x = 16
