Arthur’s dinner bill totaled $13.72, before sales tax and tip.Sales tax at the restaurant is 5.8%. After sales tax, he left a 15% tip. What was Arthur’s total bill, including sales tax and tip?
Oh Arthur, Arthur, Arthur..... You shouldn't tip the taxed amount !
Anyway ...
13.72 x 1.058 = bill amount after tax
(13.72)*(1.058) x 1.15 = total amount after tax and tip= $
