(2)  Two pounds of regular mixed nuts that are 50% peanuts contain 1 pound of peanuts.


(3)  Total mass of peanuts is 0.2 + 1 = 1.2 pounds.


(4)  Total mass of the mixture is 1 pound + 2 pounds = 3 pounds.


(5)  Now the percent of peanuts in the final mixture is  %281.2%2F3%29%2A100 = 0.4*100% = 40%.    ANSWER
