$19.60
Step-by-step explanation:
Given data
number of pages= 136 pages
number of copies = 19 copies
Hence 19 copies make a total of = 136*19
=2584 pages
hence if 500 pages cost $3.80
then 2584 pages will cost x
cross multiply
500x= 2584*3.8
500x=9819.2
Divide both sides by 500
x= 9819.2/500
x= 19.6384
x=$19.60
It will cost $19.60
