Sharing petrol costs

Modelling and explaining

Each day Dan's mum drives him to school. On the way, she picks up 3 of Dan's friends, Chris, Ben and Anne. Each afternoon, she returns by the same route and drops them off at their homes. At the end of a term, the four students decide to pay a sum of 100 pounds towards the cost of petrol. How should they share out the cost? Find some reasonable solutions and say which you think is best and why.
