Question

Ana is having dinner at a restaurant. Her bill before adding sales tax and tips is $23.20. The restaurant add the sales tax of 7% to her bill,and then Ana leaves a tip of 18% based on the new total what is Ana total cost?

Answer 1

Start by finding 7% of the $23.20:


`(7)/(100) *23.20=1.624`

Now add this to $23.20:


`23.20+1.624=24.824`

Now, let's find 18% of this new total with tax to find the tip amount:


`(18)/(100) *24.824=4.46832`

This is the tip amount. And finally, let's add this to the 24.824:


`24.824+4.46832=29.29232`

Not sure if you were given any instructions about rounding, but Ana's cost will be around $29.29.

Hope this helps.
