To find a sales tax you must multiply the percent given by the cost of the item.

1) 43.99 is the cost given

2) 7% is the tax given which is 0.07 in decimal form

3) multiply them: 43.99(0.07)

4) 43.99(0.07) = 3.0793

5) the tax is $3.07 or $3.08 if you must round

*you can also round the 43.99 to 44 to make it easier unless you were told by a teacher not to round
