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?

Respuesta :

Start by finding 7% of the $23.20:

[tex] \frac{7}{100} *23.20=1.624[/tex]

Now add this to $23.20:

[tex]23.20+1.624=24.824[/tex]

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

[tex] \frac{18}{100} *24.824=4.46832[/tex]

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

[tex]24.824+4.46832=29.29232[/tex]

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

Hope this helps.
