The typical tip would be 19.5, you get this from solving or searching up 15% of 130 equaling to 19.5
Here are two ways of doing it.
************************************************************
1) The current price is 100% of the price. The price went down by 6%, so since 100% - 6% = 94%, the new price is 94% of the original price.
94% * 175 = 0.94 * 175 = 164.50
The new price is 164.50
*******************************************************
2) The discount is 6% of 175, so first, we find the discount.
6% of 175 = 0.06 * 175 = 10.5
Now we subtract the amount of the discount from the original price.
175 - 10.50 = 164.50
The new price is 164.50
**********************************************************
As you can see, both methods give you the same answer, 164.50
