Thom's restaurant bill is $45, and he leaves a 20 percent tip. what is the total cost for thom's meal?

Multiply the price before the tip by .20

Add 9 to the total:

So, the total cost for Thom's meal is $54

The answer is $54.

Step-by-step explanation:

To find the percent, you multiply $45 by 20 percent (or 0.2). 45 x 0.2 = 9.

$9 is the 20 percent tip.

The total cost is then found by adding $9 to the $45. You then get $54.

Hope this helps! :)
