Given:
tax value = 3.60
tax rate = 5%
To solve for the tax value, we use this formula:
Tax value = Original price * tax rate
Since the original price is missing, we derive the formula from the above formula:
Original price = tax value ÷ tax rate
Original price = 3.60 ÷ 5%
Original price = 72
The original price is 72.
72 x 5% = 3.60
