Ответ:
32.94 + 15.89 + 2(19.99) = 88.81
88.81 * 0.07 = 6.2167
88.81 + 6.21 = 95.02
Lunch:
6.95 + 1.49 + 3.49 = 11.93
11.93 * 0.07 = 0.83
11.93 + 0.8351 = 12.76
Tip with tax -->
12.76 * 0.15 = 1.91
12.76 + 1.91 = 14.67
Total: 95.02 + 14.67 = 109.69
(p.s. The total would be different if Teri gave the tip to the server pre-tax)
