Please help me clear it am not getting it, sorry. Thanks 4 ur help.
 
If 20% of the original quantity is lost, remaining quantity (in this case 300 3 oz patties) must equal what percentage of the original?
 
Another approach.. If one patty weighs 3oz after 20% shrinkage (assumed from cooking), how much would a raw patty weigh?
now that you have weight of one raw patty, how much would 300 of those weigh? (if they expect an answer in pounds, don't forget to convert units)

Thanks quabache,
16 ounces = 1 pound

3 ounce is 80% of 3.75 ounce, so 3.75 ounce = 0.234 pounds.
Therefore, 0.234 pounds * 300 = 70.31 pounds

Am i right, thanks for ur help.
