at a restaurant, the bill comes to $20. you leave $24 on the table. what percent tip did you leave for the server?

Subtract to find the amount you left as a tip:

24 - 20 = 4

The tip amount was $4

Now divide the amount of the tip by the amount of the bill before the tip was added:

4 / 20 = 0.2

Multiply by 100:

0.2 x 100 = 20%

the tip was 20%

if you was gonna solve for a, a is a   < -12
