Arestaurant automatically add an 18% tip to the bill. if the tip was $9, what was the bill before the tip was added, in dollars ?

$50

Step-by-step explanation:

If the tip was $9, you can find the total price by dividing 9 by .18.  .18 is 18% but as a decimal (move to the left two decimal places).  9/.18 = 50.

You can also check the answer by finding the 18% tip of $50. 50*.18=9.
