When trying to figure up sales tax on a problem how would one write it out I have searched the site some say 1.05 some say 0.05 and something about moving a decimal over 2 spaces to the left. Im not getting it Like the problem is 3 shirts is 9.99 ea we know this is $29.97 then it says add 5% sales tax ?

  • Math -

    All of the suggestions are correct and will give you the same answer.

    Note that 5% = 5/100 = 0.05

    Here's my way.

    $29.97 times 0.05 = $1.498 = $1.50.

    The sales tax is $1.50

    29.97 + 1.50 = $31.47
