Answer

$40$ pounds of peanuts and $60$ pounds of walnuts.

Work Step by Step

Let $x$ be the amount of peanuts. Then the amount of walnuts is $100-x$. Then our equation is: $1.49x+(100-x)\cdot2.69=100\cdot2.21\\1.49x+269-2.69x=221\\-1.2x=-48\\x=40.$ Thus he mixed $40$ pounds of peanuts and $60$ pounds of walnuts.
