Refactoring - Replace Temp with Query

Motivation: You are using a temporary variable to hold the result of an expression.

public double GetDiscountedPrice()
{
    double basePrice = _quantity * _itemPrice;
    double discountFactor;
    if (basePrice > 1000) discountFactor = 0.95;
    else discountFactor = 0.98;
    return basePrice * discountFactor;
}

Refactor as:

public double GetDiscountedPrice()
{
    return BasePrice() * DiscountFactor();
}

private double BasePrice()
{
    return _quantity * _itemPrice;
}

private double DiscountFactor()
{
    if (BasePrice() > 1000) return 0.95;
    else return 0.98;
}
