12.99 plus tax is what?

Answer 1

To calculate the total cost including tax, you first need to determine the tax rate. Let's assume a tax rate of 8.5%. To find the tax amount, you multiply the cost ($12.99) by the tax rate (0.085), which equals $1.10415. Adding this tax amount to the original cost gives you a total of $14.09415. Rounding to the nearest cent, the total cost including tax would be $14.09.

Answer 2

This cannot be correctly answered without knowing the tax rate.
