$50,000

The gross domestic product is the sum of all final goods and services produced in an economy within a given period which is usually a year.
The $50,000 worth of Apples sold to individuals represent final goods. They are included as part of consumption in the calculation of GDP.
The $75,000 sold to firms which are used to produce Apple ciders are intermediate goods. Intermediate goods aren't included in the calculation of GDP.
