Step3: Calculate the increase for year 5

The increase is \(1400 - 1300=100\) stores.

Step4: Find the number of stores for year 6

From the graph, for year 6, the number of stores is approximately 1500.

Step5: Find the number of stores for year 5

From the graph, for year 5, the number of stores is approximately 1400.

Step6: Calculate the increase for year 6

The increase is \(1500 - 1400 = 100\) stores.

Answer:

The increase in the number of stores for year 5 is approximately 100 stores. The increase in the number of stores for year 6 is approximately 100 stores.
