There must be 22.5 pounds of cashews mixed with the 30 pounds of peanuts.

Explanation:

Everything is given except the the pounds of cashews, so we also don't know the total pounds.

If you let the pounds of cashews be x, then the total pounds will be x + 30.

30 (1.50) + x (5.00) = (30 + x) (3.00)

45 + 5x = 3x + 90

2x = 45

x = 22.5

There must be 22.5 pounds of cashews mixed with the 30 pounds of peanuts.
