Your customer wants to purchase 2 shirts that you sell for $15 each and a handmade necklace you sell for $13. She lives in Idaho where the state tax is 6.03%. How much should you email her as her total for the payment to you?
2 shirts x $15 each = $30
$30 + $13(necklace) =$43
$43 x 1.0603 = $45.59 - Amount that you should e-mail her.
