To determine the total cost of the jeans after applying the sales tax, you need to first calculate the amount of sales tax and then add it to the original price of the jeans.
The formula to calculate sales tax is:
Sales Tax = Price × Sales Tax Rate
In this case, the price of the jeans is $50.00 and the sales tax rate is 7.5%, which can be expressed as 0.075 in decimal form. Now, let’s do the calculation:
Sales Tax = $50.00 × 0.075 = $3.75
Now that we have the sales tax amount, you can find the total cost by adding the sales tax to the original price:
Total Cost = Price + Sales Tax
Total Cost = $50.00 + $3.75 = $53.75
Therefore, the total cost of the pair of jeans, after including sales tax, is $53.75.
