no other symbols other than the number rounded to the second decimal.

The original cost of the pair of shoes before tax is $48.95

Step-by-step explanation:

* Lets explain how to solve the problem

- Assume that the cost of the pair of shoes is 100% before taxes

∵ The cost of the pair of shoes is 100% before taxes

∵ The tax is 7.25%

∴ The price of the pair of shoes after tax = 100% + 7.25% = 107.25%

- This 107.25% equivalent to the price of the pair of shoes including

  the tax

∵ The cost of the pair of shoes including tax is $52.50

- Lets use the cross multiplication to find the cost of the pair of

 shoes before  tax

∵     100%  ⇒  107.25%

         ?       ⇒  52.50

- ? represents the cost of the pair of shoes before tax

∴ ? =

∴ The original cost of the pair of shoes before tax is $48.95
