Making change

A toy in the shop costs 10 note.

The cashier gives something back. The question: how much?

When you pay more than the item costs, you get the difference back. This is called change (or "money back").

Shop counter: customer hands a note, cashier slides coins back

The trick: count up

The easiest way is to count from the price up to the amount you paid.

Example: the toy costs 10.

8 → 10

That is 3 steps of 3.

You get $3 back.

Example with cents

Price: 5.

Counting up:

  • 4 (we need 50¢)
  • 5 (another $1)

Together: $1.50.

Another example

Price: 5.

  • 3 (we are missing 20¢)
  • 5 (another $2)

Change: $2.20.

Check: count back

Always check: price + change = amount you paid.

  • 3 = $10 ✓
  • 1.50 = $5 ✓
  • 2.20 = $5 ✓

Summary

  • Change = the money you get back when you pay more than the item costs.
  • Count up from the price to the amount you paid.
  • First fill the cents to a round number, then fill the dollars.
  • Check: price + change = amount paid.
