Explanation:
For Taxi A,
Every 40 miles would cost £35, so for 240 miles:
240 miles ÷ 40 miles = 6 (number of 40-mile trips)
6 trips x £35 per trip = £210 (original cost without discount)
With a 15% discount,
15% of £210 = £31.50 (discount amount)
£210 - £31.50 = £178.50 (final cost after discount)
For Taxi B,
240 miles x £0.70/mile = £168 (final cost)
Therefore, the cheaper taxi journey for Corey would be Taxi B, which would cost £168.
