A "score" amounts to 20. Subtract 87 from 1863 to obtain the year in question. It was 1776, which is generally regarded as the birth year of our nation.
The equation would be: 3/4x=16 1/2 So you would divide both sides by 3/4 and get 44 bags for the leftover 16 1/2 lb. of cookies. Hope this helps a lot!
