Change is a subtraction
Change = what you paid − the price. Pay with £1 for a 65p drink and your change is 100 − 65 = 35p. That is the whole idea: every change question is a subtraction wearing a costume.

Counting up instead
Shopkeepers count up from the price to what you handed over. From 65p: 5p takes you to 70p, 30p takes you to £1. So the change is 5p + 30p = 35p. Counting up is often easier than subtracting, especially near a whole pound.

Change from £5 and £10
Pay with £5 for a £2.75 notebook. Count up: 25p to £3, then £2 to £5. Change = £2.25. Breaking it into 'to the next pound, then whole pounds' works for any note. From £10 for £6.40: 60p to £7, then £3 to £10 = £3.60.

Check before you walk away
Tills and people both make mistakes. Do the count-up in your head before you leave the counter: if your notebook cost £2.75 and you paid £5, you expect about £2 back. If you are handed 25p, something has gone wrong — ask politely and count it together.

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.
