Answer:
4%
Explanation:
you invest $100,000 today and purchase A$145,137.88
in one year, you will have A$152,394.78
since the PPP stands, the spot rate in one year should be:
0.703 US$ per A$ (since Australia's inflation rate is 2% higher than the US inflation rate, the Australian dollar will depreciate by 2%)
with your A$152,394.78, you can purchase $107,133.53
if you invested in the US instead, you would have $103,000
this means that your Australian investment yielded ($107,133.53 / $103,000) - 1 = 0.04 or 4%
