Answer

question continued: what was the total amount the group paid, including tax and tip?

Answer 1

Sales tax=3.00, total paid=47.79

Explanation:

37.50 x .08=3.00 sales tax

37.50+3.00=40.50 amount with sales tax added

40.50 x .18=7.29 amount of tip

40.50 + 7.29=47.79 total with tip and sales tax
