Fatima wants to add a 20% tip on a $56 restaurant bill.

Answer:

The answer is A) Round 56 to 60, find 10%, then double.

Step-by-step explanation:

You would round to 60 because 56 is closer to 60 than 50 then 10% is half of 20% so you would double it after you found 10% of 60.

Hope this helps :)
