Question

Please could you help me.. On a Monday, all prices in Isla's shop are 10% more than normal. On Friday all

prices in Isla's shop are 10% less than normal. James bought a book on Monday for
£5.50. What would be the price of another copy of this book on Friday?​

Answer 1

£4.50

Explanation:

Due to James buying a copy that was £5.50 on a Monday when the prices are 10% more than normal. The original prices would actually therefore be £5.

This means that when the prices are 10% less than normal. The prices would actually be £4.50.

Hope this helps :)
