To calculate Louisa's total bill, including the sales tax, follow these steps:
- Calculate the sales tax by multiplying the purchase price by the sales tax rate.
- Add the sales tax to the original purchase price to find the total bill.
Step 1: Calculate the sales tax.
Sales tax = Purchase price × Sales tax rate
Sales tax = $199.00 × 0.0725 = $14.4275
Step 2: Add the sales tax to the purchase price.
Total bill = Purchase price + Sales tax
Total bill = $199.00 + $14.4275 = $213.4275
Now, round the total bill to the nearest hundredth:
Total bill = $213.43
Therefore, Louisa's total bill is $213.43.
