Explanation:

Problem 4

Step1: Determine visitors on each day

From the bar graph:

• Wednesday: Let's assume Wednesday has 10 visitors (from the graph, the bar ends at 10).
• Thursday: Let's assume Thursday has 20 visitors (bar ends at 20).
• Sum of Wednesday and Thursday: \(10 + 20 = 30\)
• Now check which day has 30 visitors. Friday's bar ends at 30.

Step1: Analyze bar lengths

Look at the bar graph. The shortest bar is for Wednesday.

Step2: Determine number of visitors

The bar for Wednesday ends at 10 (assuming the scale: 0,5,10,15,20,25,30,35). So Wednesday has 10 visitors.

Step1: Find visitors on Monday and Tuesday

• Monday: Let's say Monday has 25 visitors (bar ends at 25).
• Tuesday: Let's say Tuesday has 15 visitors (bar ends at 15).

Step2: Calculate the difference

\(25 - 15 = 10\)

Answer:

Friday
