Let pounds of lima=x and corn=y and since we want 7cents/pound lets set an equation to equal that. .09x + .06y = .07; x+y=1pound => y=1-x calculate calculate calculate and we get x=.3333 insert into equation and y=.6666. We see that x is half of y and since we require 2 pounds of corn we need 1 pound of lima beans and end up with 3 pounds of mixed vegetables . Check with .09 +.12=.21 ; .21/3=.07 Therefore we need one pound of lima beans.
