Reading a receipt

A receipt is a tiny maths sheet the shop hands you. Reading one tells you what you bought, what it cost, and whether the total is right.

The parts of a receipt

A receipt lists each item with its price, then a total, then how you paid, then any change. Here is a tiny one: Milk £1.10, Bread £1.40, Apples £1.75 — Total £4.25, Paid £5.00, Change 75p. Every line can be checked with the adding and change skills you already have.

Check the total yourself

Add the items in your head before you look at the total: £1.10 + £1.40 = £2.50, plus £1.75 = £4.25. Matches. If your answer and the receipt's total disagree, check the items again — a wrong key press can double a price.

Offers are not always cheaper

A '3 for £3' offer on yoghurts that cost 89p each saves you 3 × 89p = £2.67 versus £3.00 — only 33p. But if you only wanted one, you have spent £2.11 more than you meant to. An offer only saves money if you would have bought that many anyway.

Keep receipts for problems

A receipt is your proof. If you get home and the game case is empty or the size is wrong, the receipt is what lets the shop put it right. Grown-ups keep them for anything expensive — you can start the habit now.

The cost of a school trip

A school is planning a trip to a wildlife park. The coach costs £480 however many people go. Entry costs £9.50 for each pupil and each adult goes free. The school says every pupil must pay the same amount, and the trip must not lose money.

If 60 pupils go, the coach works out at £8 each, so the total for each pupil is £17.50. If only 40 pupils go, the coach works out at £12 each, so the price rises to £21.50. The teacher explains that the coach is a fixed cost and the entry is a cost per person — which is why the price per pupil changes when the number changes.

The school decides to charge £20 and to use anything left over for a second trip later in the year.
