How much should I tip at a restaurant if the bill is $50 and I want to leave a 20% tip?

If you want to leave a 20% tip on a $50 bill, simply multiply the bill amount by 20%, which is 0.20 in decimal form. To do this, you can either use a calculator or do it manually.

So, the tip amount would be:

$50 x 0.20 = $10

Therefore, you should leave a $10 tip on a $50 bill if you want to tip 20%.
