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.
