Question

$12.95 dinner; 15% tip

Answer 1

15% x 12.95

.15 x 12.95=1.9425

1.9425= tip

now add the tip to the dinner price

12.95 + 1.9425 = 14.8925

the total amount that you would give would be about 14.90 ( including tip )

Answer 2

`15\% \ of \ 12.95\$= (15)/(100)*12.95= (3)/(20)*12.95= \\\\ =3*0.6475 \to \boxed{1.9425\$ -the \ tip}`
