Question

Sarah wants to give the pizza delivery boy a 20 percent tip. If the pizza bill is $48.25, how much should she tip?

Answer 1

$48.25 * (20/100)

Answer 2

take 20% of 48.25 and then add that to 48.25.
Do you know how to do that ?

Answer 3

If you want to find the total cost (bill + tip) you can do
48.25*(0.2)+48.25
or
48.25*(1.2)
