Answer:
The price of a single printer cartridge is 19.69, in your given currency.
Step-by-step explanation:
First remove the tax and the software package from the total bill.
[tex]90.01 - 24.99 - 5.95 = 59.07[/tex]
Since there are 3 cartridges, you divide 59.07 by 3, giving you the price of a single cartridge.
[tex]59.07 \div 3 = 19.69[/tex]
