price in cart - tax should be calc but not displayed separately

[noameitan]

hi

 

I want to calc the tax, but it should not displayed separately.

 

c the attached pic - the price - 100 is includes the tax. but I DONT WANT the last 2 lines before the total to appear.

 

can I config it from the admin - tried but it wasn't working - the 2 lines appear or the tax was not calc and the price was like 84.

 

thanks.
