The challenge basically asks you to replace each type name with var. You have only done that with the variable 'converted'. Just make sure that each initialization really sets the var to what's expected by the current type names.

double should be,

double total = 0.0;

You need the fractional point to make it double. Otherwise its just an integer!

Not really. In your example it doesn't matter if you input 0 or 0.0 since the left side of the equal sign already states that the variable is of type double. However if declaring the variable using var you are correct.

double total = 0; // total will be a double since it is explicitly declared as a double.
var total = 0; // total will be of type int since right side is an int.
var total = 0.0; // total will be of type double since right side is a double.

The last one is the correct answer in this challenge.

You are correct if you use VS or CMD Mono but the test engine expect answers in a specific way. You need to provide them in that order to get through the challenges.
