Sales tax amount = Original price * Sales tax rate/100
Sales tax amount = $15.49 * 5.25/100

Step 2: Add the sales tax amount to the original price:
To determine the total cost, add the sales tax amount to the original price.

Total cost = Original price + Sales tax amount

Now, let's calculate the values:

Sales tax amount = $15.49 * 5.25/100
Sales tax amount ≈ $0.813225 (rounded to 2 decimal places)

Total cost = $15.49 + $0.813225
Total cost ≈ $16.303225 (rounded to 2 decimal places)
