Answer:
27 apples
Explanation:
A bar model is usually defined as the representation of numbers in the form of pictures, where the numbers are shown in the bars for calculation.
The distribution of apples is shown in a bar model that is given below, where the three separate boxes represent the baskets and each of these baskets are comprised of 9 apples.
Thus, adding all the apples from the three boxes (9+9+9), it becomes 27 apples.
Therefore, John sold a total of 27 apples.
