A mathematics exam-style question with a worked solution that can be revealed gradually
Question id: 88. This question is similar to one that appeared on an IB Studies paper in 2014. The use of a calculator is allowed.
Helena is going for a holiday to France. She changes 900 Singapore Dollars (SGD) into Euros (EUR) with no commission charged. The exchange rate between EUR and SGD is:
1 EUR = 1.49 SGD
(a) Calculate the value of 900 SGD in EUR to the nearest whole number.
At the end of Helena’s holiday in France she has 155 EUR. She converts this back to SGD at a bank, which does not charge commission, and receives 227.85 SGD.
(b) Find the exchange rate of this second transaction.
(c) Determine, when changing EUR back to SGD, whether the exchange rate found in part (b) is better value for Helena than the exchange rate in part (a). Justify your answer.
