Number of cars in the parking lot from Day 1 to Day 7, with each car icon equaling 10 cars.

Let's solve the problem step by step.

Problem:

We are given a chart showing the number of cars in a parking lot over 7 days. Each red car icon represents 10 cars, as indicated by the key.

Our task is to determine how many cars were in the parking lot on each day and possibly find patterns or total numbers.

Step 1: Understand the Key

- Each car icon = 10 cars

So, if there are 3 car icons on a day, that means:
> 3 × 10 = 30 cars

---

Step 2: Count the Car Icons for Each Day

Let’s go through each day:

#### Day 1
- Number of car icons: 7
- Cars: 7 × 10 = 70 cars

#### Day 2
- Number of car icons: 4
- Cars: 4 × 10 = 40 cars

#### Day 3
- Number of car icons: 8
- Cars: 8 × 10 = 80 cars

#### Day 4
- Number of car icons: 5
- Cars: 5 × 10 = 50 cars

#### Day 5
- Number of car icons: 2
- Cars: 2 × 10 = 20 cars

#### Day 6
- Number of car icons: 1
- Cars: 1 × 10 = 10 cars

#### Day 7
- Number of car icons: 3
- Cars: 3 × 10 = 30 cars

Step 3: Present the Results

| Day | Number of Car Icons | Number of Cars |
|-----|----------------------|----------------|
| 1 | 7 | 70 |
| 2 | 4 | 40 |
| 3 | 8 | 80 |
| 4 | 5 | 50 |
| 5 | 2 | 20 |
| 6 | 1 | 10 |
| 7 | 3 | 30 |

---

Step 4: Analyze (Optional)

You might be asked to:
- Find the maximum: Day 3 → 80 cars
- Find the minimum: Day 6 → 10 cars
- Total number of cars over 7 days:
> 70 + 40 + 80 + 50 + 20 + 10 + 30 = 300 cars

Or observe trends — e.g., the number of cars decreases from Day 1 to Day 6, then increases slightly on Day 7.

✔ Final Answer:

The number of cars in the parking lot each day is:

- Day 1: 70 cars
- Day 2: 40 cars
- Day 3: 80 cars
- Day 4: 50 cars
- Day 5: 20 cars
- Day 6: 10 cars
- Day 7: 30 cars

Total over 7 days: 300 cars
