To calculate Louisa's total bill after including sales tax, we first need to calculate the sales tax on the snake she purchased.
-
Calculate the sales tax: \[ \text{Sales tax} = \text{Price} \times \text{Sales tax rate} \] \[ \text{Sales tax} = 199.00 \times 0.0725 = 14.3775 \]
-
Calculate the total bill: \[ \text{Total bill} = \text{Price} + \text{Sales tax} \] \[ \text{Total bill} = 199.00 + 14.3775 = 213.3775 \]
-
Round to the nearest hundredth: The total bill rounded to the nearest hundredth is: \[ \text{Total bill} \approx 213.38 \]
Thus, Louisa's total bill is $213.38.
