The problem

Sam bought some lunch for his family which cost $13.65.

He paid using a 20 dollar note.

How much change will he receive?

  • $6.35
  • $6.45
  • $7.35
  • $7.45
a 20 dollar note

Investigate

As Sam put his change in his pocket, he realised he had been given 1 note and 4 coins.

He wondered... what other quantities could I make with one $5 note and 4 more coins?

  • What’s the smallest amount of money I might have?
  • What's the largest amount of money I might have?
  • How many possibilities are there?
