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
Aneli [31]
Start by finding 7% of the $23.20:

\frac{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:

\frac{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.
