So start with $12.49 as the cost of the soup. Simply, as found in a calculator or by taking 12.49x.12, you can find the cost of the tax itself. With this, you get 1.4988 which rounds to $1.50 in U.S. currency. Add $12.49 + $1.50 and the answer is: $13.99

Well first you need to set up a proportion....

.12 x

100 12.49

149.88 divided by 100x
you should get 1.4988 which is 1.50
that is the tax.
now add 1.50 and 12.49 to get 13.99 as the total

Answer:

26 wins , 14 ties

Step-by-step explanation:

Given: Hockey teams receive $2$ points when they win and $1$ point when they tie. One season, a team won a championship with $66$ points. They won $12$ more games than they tied.

To Find: How many wins and how many ties did the team have.

Solution:

let the number of wins hockey team have $=\text{x}$

let the number of ties hockey team have $=\text{y}$

Now,

Hockey teams receive $2$ points when they win and $1$ point when they tie.

$2\text{x}+\text{y}=66$

They won $12$ more games than they tied

$\text{x}-\text{y}=12$

Solving both equations we get

$\text{x}=26$

$\text{y}=14$

Hence, the hockey team have $26$ wins and $14$ ties.
