Sorry its been a long time since ive been out of school and math was never my subject. anyway here is the problem. Please help!!!
Suppose it costs twice as much to print a single copy of
a handbook on demand as it costs to print each copy
when they are printed in volume. What fraction of the
students must use alternative access methods in order
for the university to save 21 percent of its printing cost
for handbooks overall? What if the cost ratio of single-
copy printing to the cost of each copy when printed in
volume is 5:1? If 85 percent of the students access
handbooks online, how much more expensive can
single-copy printing be for the university to break
even on printing handbooks?
