Given:
Farmer's price = $1
Miller's price = $3
Baker's price = $6
To find:
The value added by the miller
Solution:
From the given, we can interpret that after purchasing from the farmer, the miller turns the wheat into flour by grinding and he sells the wheat flour to the baker.
This means that the miller added the cost of grinding with the purchasing cost. We can calculate the cost added by miller by subtracting the farmer's price from the miller's price that is
Therefore, the value added by the miller is $2.
