The image shows a line graph titled *"A line graph to show the number of parcels delivered"*. The x-axis represents the days of the week, from Monday to Sunday, and the y-axis represents the number of deliveries, ranging from 0 to 140.

Task:


We are asked to solve the problem related to this graph. Since no specific question was provided in your message, I will interpret the task as analyzing the data shown and possibly identifying key information such as:

- The number of deliveries on a specific day
- The highest and lowest delivery counts
- Trends over the week

Let’s analyze the graph step by step.

Step 1: Read the Data Points



From the graph, we can extract the approximate number of deliveries for each day:

| Day | Number of Deliveries |
|---------|----------------------|
| Mon | 120 |
| Tue | 120 |
| Wed | 102 |
| Thu | 110 |
| Fri | 100 |
| Sat | 125 |
| Sun | 100 |

> Note: The value for Wednesday is explicitly labeled as 102, with a dashed line pointing to it.

Step 2: Identify Key Observations



- Highest deliveries: Saturday (125)
- Lowest deliveries: Friday and Sunday (both 100)
- Trend:
- Delivery numbers drop from Tuesday to Wednesday.
- Then rise on Thursday, dip on Friday, peak on Saturday, and fall again on Sunday.
- Most consistent days: Monday and Tuesday both have 120 deliveries.

Step 3: Possible Questions & Answers



Since no explicit question was given, here are common types of questions that might be associated with this graph:

#### Q1: How many parcels were delivered on Wednesday?
Answer: 102 parcels.

#### Q2: On which day were the most parcels delivered?
Answer: Saturday (125 parcels).

#### Q3: What is the difference between the highest and lowest number of deliveries?
Answer:
125 (Sat) – 100 (Fri/Sun) = 25 parcels

#### Q4: Did the number of deliveries increase or decrease from Monday to Wednesday?
Answer:
Monday: 120 → Tuesday: 120 → Wednesday: 102
So, it decreased from Tuesday to Wednesday.

#### Q5: Which days had the same number of deliveries?
Answer:
- Monday and Tuesday (120 each)
- Friday and Sunday (100 each)

Final Summary



The graph displays weekly parcel delivery trends.
