Assuming you had a bill of $120 when you went to the restaurant with your three friends, the 20% tip would come out to $24.
First assume an amount that the meal you ate cost. Let's assume that amount if $120.
If the tip rate if 20%, it means that you need to find out what 20% of the bill of $120 is.
If you don't want to use a calculator, there are other ways you can calculate the tip.
An easy method would be to find 10% of the bill. To find 10%, all you have to do is to move the decimal point from right to left.
The decimal point in $120 is at the far right so the 10% amount would be:
= $12.0
Now that you have the 10% amount, remember that 20% is simply twice the amount of 10% so:
= 12 x 2
= $24
The total amount then becomes:
= 120 + 24
= $144
In conclusion, your tip amount would be $24.
