You give a delivery driver $15.50 for a pizza that costs $12.50. You tell the driver to keep the change as a tip. is the tip more or less than 20%?

The tip is greater than 20 percent

Step-by-step explanation:

The price of the pizza is 12.50

If you give a 20% tip

tip = original price times tip rate

tip = 12.50 * 20%

= 12.50 *.20

= 2.50

He gives the driver 15.50

15.50 - 12.50 = 3 dollars which is the tip

3 > is greater than 2.50

The tip is greater than 20 percent

The pizza costs $12.50 and 20% of 15.50 is $12.40

so you gave more then 20% to the driver.
