Outback automatically applies an 18% gratuity on parties larger than 12 people. You went to dinner with a group of 20 people and the bill was $246. What is the total cost of the bill, including the gratuity?

$290.28

Step-by-step explanation:

To find tip, you need to multiply the cost ($246) by the desired tip amount in a decimal (0.18). 246*0.18=44.28

Once you have done that add that number to the cost. $246+$44.28=$290.28

If you don't know how to convert a percent to a decimal, you divide the percent by 100.
