6.25*20pound=125
6.50*15pound=97.5(cashews)
5.50*5pound=27.5 (peanuts)
97.5+27.5=125
Cashew = 15pounds
Peanuts = 5pounds

assuming no mark-ups, Let C be the pounds of cashews. 20-C is the pounds of peanuts.
Proceeds of mix sale = proceeds from C pounds of cashews + 20-C pound of peanuts.
Stick in the numbers:
20 x 6.25 = +
and solve for C

cashews pounds=x
penanuts pounds=y
x+y=20
6.50*x+5.50*y=(6.25)(x+y)
Let us find the solution:
650x-625x=625y-550y
x=3y from the second equation.
then
3y+y=20
y=5
x=15

6.5x + 5.5y = 6.25*20
x + y = 20
6.5x + 5.5y = 125
5.5x + 5.5y = 110
x = 15 lb cashews
y = 5 lb peanuts
