Final answer:
The car, which was bought for £1800 and is now worth £1602, is currently worth 89.01% of its original cost.
Step-by-step explanation:
To find this, we divide the current value, £1602, by the original cost, £1800, and then multiply by 100 to get the percentage:
Percentage = (Current Value ÷ Original Cost) × 100
= (£1602 ÷ £1800) × 100
= 0.8901 × 100
= 89.01%
Thus, the car is now worth 89.01% of its original cost.
