Answer:
The Value added of the Baker is $0.25
The sum of the value added at each stage of production is :
Farmer = $0.15
Miller = $0.20
Baker = $0.25
Grocer = $0.20
Total Value added = $0.80
Explanation:
Farmer cost = $0.20
Farmer Margin = $0.15
Farmer Sells to Miller = $0.35
Miller Margin = $0.20
Miller sells to Baker = $0.55
Baker Margin = $0.25
Baker sells to Grocer = $0.80
Grocer Margin = $0.20
Grocer sells to Family = $1.0
The concept of Value added states that a product receives extra features from the beginning of its production cycle to when it gets into the hands of its final consumers. The process of it being handed down through the Value Chain results in changes in Prices between the Input Costs and selling Prices. This difference is identified as Value added.
In this question, the Farmer added Value by turning a seed of wheat to a harvest of wheat which he sold to the Miller. The Miller further added Value by transforming the wheat into flour and selling this to the Baker. The Baker adds value by producing a product the consumer needs and selling to the Grocer, in his case bread. The Grocer added value by making it available on the shelf and within the neighborhood of the consumer.
This is how value is added. And it varies per product and per channel of distribution too.
