Error 1 Cannot implicitly convert type 'double' to 'int'. An explicit conversion exists (are you missing a cast?) [closed]

Answer 1

tax is an int and you are trying to assign it a float value.

You either have to declare tax as a float / double / decimal or somehow round its value.

EDIT: It's also weird how you don't initialize the value of money, use Console.ReadLine(), and parse its return value

Answer 2

Change your variable tax to double

  double tax = 0;

Working Code,

Console.Write("Input money : ");
float money = Console.Read();          
double tax = 0;
if (money < 10000)
{
    tax = .05 * money;
}
else if (money <= 100000)
{
    tax = .08 * money;
}
else
{
    tax = .085 * money;
}

Console.WriteLine("Tax is {0}", tax);
Console.ReadLine();
