Answer 1

your syntax is just a little off (missing parentheses after function call and no return type specified for your function).

if (checkBox1.Checked == true)
    rental = dayrental() * 19.95;

public double dayrental()
{
    var timeSpan = dateTimePicker2.Value - dateTimePicker1.Value;
    return (double) timeSpan.Days;
}
