Step by step explanation: 1) To find the sales tax, 70 is your 100% So since you’re trying to find the sales tax, you add the 3% to the 100%, which gets you to 103%. 2) Now you turn 103 to a decimal (if you want to. This is my preferred option to make this easier) 3) 103 turns into 1.03. 4) Now you multiply 70 and 1.03.
