If you eat in a restaurant and your bill is 45$. what percent tip will you leave?( Assume the service was good) How much will that be? what is the total?
Some people do 15%-20%. or double the tax on the bill. What I would do is 20%, that would be 45*20%=9 or for. so the total would be $54. for 15% you would calculate 15%*45=6.75, so the total would be $51.75.
