Answer 1

Hi TTD

If total = 110.00 including 20% tip for Miss Sally then

Let x = cost of service

Let 0.20x = Miss Sally's tip

110 = x + 0.20x

110 = 1.20x

110/1.20 = x

91.67 = x

91.67 x 0.20 = 18.33 for Miss Sally

18.33/91.67 * 100 = 19.99%

If total 110 = before tipping Miss Sally then

110 * 0.20 = Miss Sally's tip

$22 = Miss Sally's tip

Answer 2

Hey! This is an awesome real life situation. To answer this question what you'll need to do is multiply 110 by 20%. 110*.20 Therefore your tip will be $22!
