Sales tax in the state of California is 9.25%. After shopping at a Shmarget in Laguna Beach, your purchases came to $62.75, before tax. How much do you end up paying, including tax?

Add the 9.25% sales tax. In order to do that, find 9.25% of $62.75. 

Here it is set up as a proportion.   

Now, cross-multiply and divide.

This is the sales tax.

Finally, add the sales tax to the total.

$5.80 + $62.75 = $68.55

That's your total bill. Thanks for shopping at Shmarget!
