To calculate Louisa's total bill for the snake, including sales tax, you can follow these steps:
-
Calculate the sales tax: \[ \text{Sales Tax} = \text{Price} \times \text{Tax Rate} = 199.00 \times 0.0725 \]
\[ \text{Sales Tax} = 199.00 \times 0.0725 = 14.3775 \]
-
Round the sales tax to the nearest hundredth: \[ \text{Rounded Sales Tax} = 14.38 \]
-
Calculate the total bill: \[ \text{Total Bill} = \text{Price} + \text{Sales Tax} = 199.00 + 14.38 = 213.38 \]
Therefore, Louisa's total bill, rounded to the nearest hundredth, is $213.38.
