Final answer:
a. £128 The correct answer is £128 for the price of the return ticket, calculated using the given 8% saving on a return ticket compared to two single tickets, and the £20.48 difference in price.
Step-by-step explanation:
The correct answer is option a. £128 is the price of the return ticket. To find this, we start with the information that the saving on the return ticket compared to two single tickets is 8%, and the difference in price is £20.48. If we let the total cost of two single tickets be x, then the return ticket costs x - £20.48.
Since the return ticket offers an 8% saving, we can say that x - (0.08x) = x - £20.48. Simplifying this equation, we get 0.92x = x - £20.48. Solving for x gives us x = £20.48 / 0.08, which results in x = £256 for two single tickets. Therefore, the price of the return ticket is £256 - £20.48 = £235.52.
