Question

How do I find the cost for the sales tax if the price is $7 and the sales tax is 8% or 0.08

Answer 1

Do 7 times 0.08.  You should get 0.56. That's the tax

Answer 2

Multiply 7 by 0.08 and you get $0.56. $0.56 is the tax. For other tax questions just multiply the price and the sales tax as the decimal.
