Scarlett has £2. The difference is 45p.
4. Yasin has two more silver coins in his pocket. Which coins would they need to be so that they have enough money to watch the film?
Discuss which silver coins Yasin could have. Discuss if there are any combination of silver coins which, when added to Scarlett’s £2, would give them enough to watch the film. This question is open-ended for the children to explore.
Various answers, for example: Yasin could have any combination of 5p, 10p, 20p and 50p coins. If Yasin has a 50p coin and any other silver coin, they would have enough money to watch the film.
