Today, 5 friends went out for lunch. their total bill was $36.10, including tax and gratuity. they decided to split the bill equally and each paid with a $10 bill. how much money will each person get back?

Total spend = 36.10

one person's pay = 10

five persons' pay = 50

Extra amount

50 - 36.10

13.90

To distribute evenly, that extra amount has to be divided by 5

13.90 / 5

2.78

Therefore each person will get the money as $2.78
