Question

The first photocopy of an original costs 8 cents, the second through tenth copies cost 6 cents each, and each additional copy after the tenth costs 5 cents. if a woman spent 92 cents on copies of one original, how many copies did she receive?

Answer 1

The cost for more than 10 copies is essentially 5¢ each plus 12¢, so for 92¢, the number of copies is (92-12)/5 = 16.

The woman received 16 copies of her original.
