If there is 6 percent sales tax, that means for every dollar the item you bought was ($18) there will be 6 cents added to it.  So you would take 6 percent of or times 18 dollars which is 1.08.  Then add those two together to get 
Final answer.  The stereo is $19.08 dollars.

Set up like 0.06x = 18. So if Amanda buys a $300 stereo and sales tax is 6%, tax is $18
