What design pattern do I use for this?

Say I am modelling this scenario - what design pattern could I use to best model this?

The base class is a CellPhonePlan. CellPhonePlan has two properties:

Where StandardFeatures might include a value such as "200 minutes call time".

I also want to provide some addons to the standard CellPhonePlan. Such as

1) Family Plan

2) WeekendPlan

I want to be able to choose the StandardFeatures, FamilyPlan and WeekendPlan and have its price and features reflective of the options I have made. I also would like to know how to best represent this using a design pattern!

Thanks

Sorry I guess I didn't explain that too clearly. What I am after is having the base plan plus the family, plus the weekend. So all the values add up.

This looks like it could fit well into the Decorator pattern, if you really want to use a design pattern.

No design pattern needed...

class CellPhonePlan
{
    int MonthlyPrice { get; set; }
    List<string> Features { get; set; }
}

var standardPlan = new CellPhonePlan
{
    MonthlyPrice = 10,
    Features = new List<string>() { "200 minutes call time", "texting" }
};

var familyPlan = new CellPhonePlan
{
  MonthlyPrice = 20,
  Features = new List<string>() { "500 minutes call time", "texting", "shared between a family" }
};

var weekendPlan = new CellPhonePlan
{
  MonthlyPrice = 5,
  Features = new List<string>() { "200 minutes call time", "but you can only talk on weekends" }
};
