" At sams soup shop, the price of a bowl of chicken noodle soup costs $12.49 if there was 12% tax on top of the cost of the soup, how much would one bowl of soup cost? "

Respuesta :

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
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
