Final answer:
The percentage loss on the iPod is calculated by finding the difference in the original and sale prices then expressing that difference as a percent of the original price, which is 27.5% in this case.
Step-by-step explanation:
To find the percentage loss in the price of an iPod, you need to follow these steps:
Calculate the difference in price between the original price and the sale price: £200 - £145 = £55.
Determine the loss as a percentage of the original price: (£55 / £200) * 100 = 27.5%. Therefore, the percentage loss on the iPod is 27.5%.
