Stephanie has just finished her meeting in Australia. Before going back home to Thailand, she decided to have a short vacation in Pulau Langkawi. Upon arrival, she bumped into Alex, her unversity classmate at the baggage claim. They decided to catch up over coffee while Alex is waiting for his connecting flight. Heading to the cafe, Stephanie wanted to stop at the currency exchange desk since she still has a balance of A$350, worth $0.75 from her Australia trip. The airport foreign exchange shows a quote spread of $0.6501-$0.6506. Coincidently, Alexs sister had asked him to exchange some Australian dollars since she will be going to study there. Looking at the currency exchange, he offered to buy from Stephanie all her Australian dollars for RM1890, since the exchange desk selling RM for $0.1211-$0.1216. Should Stephanie accept Alexs offer?
