Problem Analysis:
The task involves analyzing a tally chart to determine the frequency of sales for different food items (Burger, Pizza, Fried Chicken, and Hot Dog) sold by Laila, a café owner. We need to fill in the frequency table and answer three questions based on the data.
#### Step 1: Count the Tally Marks
Each tally mark represents one sale. A group of five tally marks is represented as "|||||". Let's count the tally marks for each food item:
1.
Burger:
- Tally marks: |||| |||| |||| |
- Total: \( 5 + 5 + 5 + 1 = 16 \)
- Frequency: 16 (already given)
2.
Pizza:
- Tally marks: |||| |||| |||| |||| |||
- Total: \( 5 + 5 + 5 + 5 + 4 = 24 \)
- Frequency: 24
3.
Fried Chicken:
- Tally marks: |||| |||| ||
- Total: \( 5 + 5 + 2 = 12 \)
- Frequency: 12
4.
Hot Dog:
- Tally marks: |||| |
- Total: \( 5 + 1 = 6 \)
- Frequency: 6
#### Updated Frequency Table:
| Food Items | Tally Marks | Frequency |
|------------------|----------------------------|-----------|
| Burger | |||| |||| |||| | | 16 |
| Pizza | |||| |||| |||| |||| ||| | 24 |
| Fried Chicken | |||| |||| || | 12 |
| Hot Dog | |||| | | 6 |
Step 2: Answer the Questions
#### Question 1: Which food item was sold the least (very less)?
- From the frequency table:
- Burger: 16
- Pizza: 24
- Fried Chicken: 12
- Hot Dog: 6
- The Hot Dog has the lowest frequency (6).
Answer: Hot Dog
#### Question 2: How many Burgers and Fried Chicken were sold altogether?
- Frequency of Burgers: 16
- Frequency of Fried Chicken: 12
- Total: \( 16 + 12 = 28 \)
Answer: 28
#### Question 3: How many more Pizzas were sold as compared to the Hot Dog?
- Frequency of Pizzas: 24
- Frequency of Hot Dogs: 6
- Difference: \( 24 - 6 = 18 \)
Answer: 18
Final Answers:
1.
Which food item was sold the least?
\[
\boxed{\text{Hot Dog}}
\]
2.
How many Burgers and Fried Chicken were sold altogether?
\[
\boxed{28}
\]
3.
