Answer:
First snack contains 80 lb.
The second snack contains 60 lbs
Explanation:
We know in the end , both bags must be even and equivalent to 140 once totaled. This means the sacks would indeed be 70lb following subtracting 1/8 the first.
We can make the first bag 80 lb by adding 10 lb to it. That means we'd have to subtract 10 lb from the next sack, bringing it to 60 lb. We assume we can achieve it since 140 is the what you get when you do 80+60.
10 is the answer of 1/8 of 10. So remove 10lb from the first sack and put it in the second, and both bags are even at 70lb, and their total is 140lb.
This suggests that the very first sack is 80 lbs and the second one is 60 lbs.
