Question

How do you do the work for

$43 dinner; 18% gratuity

Answer 1

Start by calculating just the gratuity by itself. We know its 18% of $43. Another way to write 18% is 0.18 so:

`G=$43 * 0.18`

`G=$7.74`

So just the gratuity by itself is $7.74. If you want to know the entire bill you can add up the meal and the gratutiy like so


`T= Meal + Gratuity`

`T = 43 + $7.74 = $50.74`

Another way to do it is to recognize that you are paying for 100% of the meal and then paying antoher 18% AGAIN for a total of 118% or 1.18. If you do this you get the same answer:


`$43 * 1.18 = $50.74`

Answer 2

The total cost of the dinner with gratuity is $50.74Add the gratuity to the regular price. Method 2: Add the percent of gratuity to 100%. 100% + 18% = 118% The total cost is 118% of the bill. Method 1: Add gratuity to the regular price. Find the gratuity.
