How do you find the sales tax of something? Here is one of my problems:
The price of three dolls are $12.99. What is the price of the dolls with a 5% sales tax? Show all of your work!
I cannot figure out how to put up an equation and solve this problem. Please help!

Ms. Sue,
12.99 * 1.05 = x
or  if the dolls cost 12.99 each  then 
3(12.99)(1.05) = x

Lila,
thanks but its
12.99*0.2 = 2.60 discount
12.99  2.60 = 10.39 new price
10.39 * 0.05 = 0.52 tax
10.39 + 0.52 = 10.91 price for each dolls
