Find the total cost of a $363.99 airline ticket with a sales tax of 5%.

$382.19

Work: So, we need to multiply $363.99 with the sales tax. So, we are going to multiply $363.99 by .05. Reason for this is because you need to move the decimal back two spots. So, after multiplying, you get 18.1995. We are going to round this to 18.20. Now, we add that to $363.99, and you get $382.19.

I hope this helps, and Happy Holidays! :)
