Question

Your family goes to a restaurant and the bill for dinner comes to $62.00. (including tax). If you decide to leave a 15% tip, how much will the total bill come to?

Answer 1

What you need to do is just multiple 15% to $62. 
15% means 15/100
15% X 62= 9.3
So you pay $62+$9.3= $71.3

Answer 2

62 x .15=9.30
62.00 +9.30=$71.30
