Fascinating Fact:

A restaurant bill comes to £72 before service. A 12.5 percent service charge is added, making the total £81.

In 11 Plus Maths, pupils learn how percentages can increase or decrease amounts. Understanding service charges, discounts, and tips helps apply maths confidently in daily life.

  • Service Charge: An extra amount, usually a percentage, added to a bill for staff service in a restaurant.
  • Percentage: A way of expressing part of a whole, where the total equals 100.
  • Total Bill: The combined amount including the original cost and any added charges.
How do you calculate a 12.5 percent service charge?

Find 10 percent of the bill by dividing by 10, then add half of 5 percent. Add this amount to the original total for the final cost.

Why do restaurants add a service charge?

Service charges reward staff for their service and save customers from calculating tips separately. They’re often shown clearly on the bill.

Is a service charge always compulsory?

In many restaurants it’s optional, especially if marked “discretionary.” Customers can ask to remove it if they prefer to tip directly.

Jill bought a bucket for £11.89. She paid with a £50 note, and was given £33.11 in change. By how much was she short changed?
£5.00
£6.00
£7.00
£8.00
If you get short changed, it means that you have been given less change than you should have been given.
£50 - £11.89 = £38.11 which is £5.00 more than the change Jill was given, ? she was short-changed by £5.00

If 19 items cost £142.50, how much will 7 items cost?
£17.50

Now we find the cost of 7 items: 7.5 x 7 = 52.5
Remember that, when dealing with money, decimals should be given to 2 places: 52.5 = £52.50
