Luisa purchased a new snake for $199 sales tax is 7.25. What is her total bill?

To find the total bill, we need to calculate the sales tax and add it to the cost of the snake.

First, let's find the amount of sales tax:
Sales tax = (7.25 / 100) * $199 = $<<7.25/100*199=14.4275>>14.43

Now, let's calculate the total bill:
Total bill = Cost of snake + Sales tax = $199 + $14.43 = $<<199+14.43=213.43>>213.43

Therefore, Luisa's total bill is $213.43.
