Question

How much will the bill be without the service charge?

You receive the bill for a meal at a restaurant. The total for the meal, including a discretionary 10% service charge, is £61.60.
You feel that the service you received was poor, and you ask for the service charge to be removed from the bill.
How much will the bill be without the service charge?

Answer 1

The original bill (without the added charge) is 56.00

Explanation:

10% was added to the bill and that made it 61.60

So 61.60 = 110% of the original bill.

If the original amount was x, then

61.60 = 1.10x

x = 61.60/1.10

x = 56.00
