Let the number of pounds of cashews be x.

Now, we are told that A nut store normally sells cashews for​ $4.00 per pound. Thus;

Cost of x pounds of cashews = $4x

He wants to mix the above with 90 pounds of peanuts and sell the mixture for $3.5 per pound. Thus, the equation here is;

((90 * 1.5) + (4x))/(x + 90) = 3.5

135 + 4x = 3.5(x + 90)

135 + 4x = 3.5x + 315

4x - 3.5x = 315 - 135

0.5x = 180

x = 180/0.5

x = 360 pounds of peanuts
