    A child’s bus fare is cheaper than the adult fare but is more than half the adult fare. The total cost of a single journey for an adult and two children is £1.20. Adult fares are all multiples of 10 p.

    2. What is the adult fare?
    • 0
    0

    Explanation

    The correct answer is C.

    A child’s bus fare is cheaper than the adult fare but is more than half the adult fare: 0.5a<c<a. The total cost of a single journey for an adult and two children is £1.20: a+2c=1.20. We can substitute the values given from A-E into both equations until we get an answer that satisfies both equations. E.g for answer A we substitute ‘a’ with 0.30: 2c=1.20-0.30=0.90, so c=0.45, which does not satisfy 0.15<c<0.30, therefore A is not the correct answer. Only answer C satisfies both equations, 2c=1.20-0.50=0.70, so c=0.35, which satisfies 0.25<c<0.50, so is the answer.
