Answer:
3.25 pounds
Explanation:
Starting with 25 pounds we trim off 35%:
25 X .35 = 8.75 trimmed off
This leaves 25 - 8.75 pounds of trimmed meat:
25 - 8.75 = 16.25 of trimmed meat.
During cooking we lose another 80% of the weight of the meat:
16.25 X .80 = 13 pounds "cooked off"
So the remaining weight of meat is 16.25 - 13:
16.25 - 13 = 3.25 pounds of trimmed cooked meat.
How sad is that?
