What a nightmare - Mr Zopa is here again.

Bandy wants to buy a branded  Mochi handbag. The recommended retail price of the handbag is $1,800.
Bandy has $500 saved from winning a lucky draw earlier this year, and she has been working part-time on 4 weekends, earning $250 each weekend.
After collecting her salary, Bandy went to RobinHood, a shop selling branded bags, as she heard that Robinhood is selling branded bags at 15% off retail prices. She was dismayed when she learnt from the salesgirl that the bag was $1,700.
The cost price of the bag to Robinhood is $1,500. However, Mademoiselle  Mochi dictated that the bag must not be sold at more than 10% discount off its recommended retail price.
Bandy and the salesgirl at Robin Hood want to negotiate the price of the bag.
