How can I calculate that on the day customer returns the vehicle?

float LfExtraMilage = (LfEndMilage - LfStartMilage) - (150 * (LiNumberOfDays + 1));

float distance = 215;
float overhead = distance - 150;
if(overhead > 0)
{
   float extraMiles = (int)(overhead / 10) + Math.Sign(overhead % 10);
   float price = 35 * extraMiles;
}

var fee = Math.Max(mileage - 150,0) * 35;

The backspace button is supposed to remove the last value entered by the user but how do I do that ?

lblDisplayPanel.Text = lblDisplayPanel.Text.Remove(lblDisplayPanel.Text.Length - 1, 1);
