<PRE><B>Question 813491</B>
Printer ink costs $23.42 per cartridge if bought separately. If bought by the case of 24 cartridges, the cost per cartridge is only 19.53. about how much is the difference in the cost of buying 4 cases than buying the same number of cartridges separately????????
-----
For one cartridge the difference is 23.42-19.53 = 3.89
For one case the difference is 24*3.89 = 93.36
--
For 4 cases the dfference is 4*93.36 = $280.08
