This is because when using the distribitive property they did not multiply the 1 in parenthese which would be x-5x+5=3x+2
For the cost to be the same:
18648+23.5b=83556+10b subtract 10b from both sides
18648+13.5b=83556 subtract 18648 from both sides
13.5b=64908 divide both sides by 13.5
b=4808
So if 4808 books are produced the cost of both methods is the same.
