Answer 3

Call 1 pound of cashews c and one pound of peanuts p. Now make equations based on what you know about them.

3c+4p=25.75

Solve one of your equations for either c or p. Now, in the equation you didn't solve for one variable, replace that letter with what you came up with. Then solve for that letter.
