Nancy has cash to buy 1000 bags of 2kg plain flour today. She wants to invest her money so that she can afford 1040 bags of the same flour after one year. The selling price of the flour per bag is $1.50 today. Assume the price will be $1.53 after one year. Which of the following (using the exact version of the Fisher Equation) is the lowest nominal return p.a. Nancy should earn to achieve her goal?
