where exactly is the error? Btw you should use (int, double, double) instead of Tuple<int, double, double>

The two last Console.Writeline

You have a typo {0] should be {0} although you should use $interpolation instead

String interpolation is the preferred way of building strings in C#. It is easier to read than concatenation. For example:

var foo = 1;
var bar = 2;
Console.WriteLine("foo is equal to: " + foo + " and bar is equal to: " + bar);

var foo = 1;
var bar = 2;
Console.WriteLine("foo is equal to: " + foo + " and bar is equal to: " + bar);

can be written as:

var foo = 1;
var bar = 2;
Console.WriteLine($"foo is equal to: {foo} and bar is equal to: {bar}");

var foo = 1;
var bar = 2;
Console.WriteLine($"foo is equal to: {foo} and bar is equal to: {bar}");
