Question

Brandon buys radio for 43.99 in a state where the sales tax is 7% how much does he pay in taxes?

Answer 1

43.99 times 7% in decimal form which is 0.07 then it equals 3.0793 and if you want how much it would coat then you add 3.0793 and 43.99 I hope that helped

Answer 2

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
