x of the first with .30pk+.70p
x+25 of the second with .40pk+.70p.
Total is 2x+25(.38)=.76x+9.50
.30x+.40(x+25)=.76x+9.50
.30x+.40x+10=.76x+9.50
0.5=0.06x
50=6x
x=8 1/3 oz of the first--.30(8.33)=2.50 oz pecans
x+25=33 1/3 oz of the second=.40(33 1/3)=13.33 oz pecans
That would be 41 2/3 oz with 15.83 oz pecans, and that is 38%.
