Kyles meal at the dinner costs $21.05 he wants to leave a 15% tip about how much should the top be?

Answer: $3.16.

Step-by-step explanation:

You want to leave a 15% tip on a meal that cost $21.05.

First, convert the 15% to an actual number that can be used in a calculation. For percents, this is always done by simply dividing the percent (in this case 15%) by 100%. So, the conversational term "15%" becomes 15% / 100% = 0.15 in terms of a real mathematical number.

Second, you need to find out what 15% of your $21.05 meal cost is. This is always done by multiplying 0.15 by $21.05, or

0.15 x $21.05=$3.16.

So, the amount of tip you are going to leave is $3.16.
