This is a .net core 2.2 console application that takes an amount and returns an interest rate base on the amount.

Using CLI inside the solution folder

dotnet build (to build the both projects)
dotnet test (to run the tests)
dotnet run  --project .\InterestCalculator\InterestCalculator.csproj (to run the app)

• Data Access: This is a mock repository to save and retrieve the interest rates. In a real case scenario this could be a database or a cache storage.
