To calculate the total cost of the purchase, you'll need to add the sales tax to the original price. Here's how you can do it:
Step 1: Calculate the sales tax amount:
To find the sales tax amount, multiply the original price by the sales tax rate. In this case, the original price is $15.49 and the sales tax rate is 5.25%.
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)
So, the total cost of the purchase would be approximately $16.30.
