what is the total bill if a large pizza is $16.25, tax is 3% and you tip the waiter 20%​

Answer:You want to leave a 15% tip on a meal that cost $16.25.First, convert the 15% to an actual number that can be used in a calculation. For percents,this is always done by simply dividing the percent (in this case 15%) by 100%.So, the conversational term "15%" becomes 15% / 100% = 0.15 in terms of a real mathematical number.Second, you need to find out what 15% of your $16.25 meal cost is.This is always done by multiplying 0.15 by $16.25, or0.15 x $16.25=$2.44.So, the amount of tip you are going to leave is $2.44.This makes the total cost of your meal (to write on your charge slip or other payment)$16.25 + $2.44 = $18.69.
