kim had a meal at the downtown diner which cost $14.98. if she tips 15%, how much tip should she leave? round to the nearest cent.

Tenth grade algebra? And you don't know how to figure the tip??? Something is wrong with this picture.
Using a calculator, multiply:
14.98 * 0.15 = 2.247 = $2.25
I usually do approximate figuring in my head.
10% of 15 = 1.5
Double 1.50 = 3.00
Halfway between 1.50 and 3.00 is 2.25.
