Answer 2

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
