Problem Analysis:
The task involves solving a series of subtraction problems based on the sales data of three types of herbal tea (Mint, Ginger, and Chamomile) for one day, split into morning and afternoon sales. The total sales for each type of tea are provided, and some data is missing. We need to use subtraction to find the missing values and answer the questions.
Given Data:
-
Total Sales:
- Mint: 964 packets
- Ginger: 743 packets
- Chamomile: 687 packets
-
Morning Sales:
- Mint: 683 packets
- Ginger: 502 packets
- Chamomile: ? (missing)
-
Afternoon Sales:
- Mint: 251 packets
- Ginger: ? (missing)
- Chamomile: 356 packets
Steps to Solve:
#### 1.
How many packets of ginger tea were sold in the afternoon?
- Total Ginger sales = 743 packets
- Morning Ginger sales = 502 packets
- Afternoon Ginger sales = Total Ginger sales - Morning Ginger sales
\[
743 - 502 = 241
\]
-
Answer: 241 packets of ginger tea were sold in the afternoon.
#### 2.
How many packets of chamomile tea were sold in the morning?
- Total Chamomile sales = 687 packets
- Afternoon Chamomile sales = 356 packets
- Morning Chamomile sales = Total Chamomile sales - Afternoon Chamomile sales
\[
687 - 356 = 331
\]
-
Answer: 331 packets of chamomile tea were sold in the morning.
#### 3.
How many more packets of mint tea were sold in the morning than in the afternoon?
- Morning Mint sales = 683 packets
- Afternoon Mint sales = 251 packets
- Difference = Morning Mint sales - Afternoon Mint sales
\[
683 - 251 = 432
\]
-
Answer: 432 more packets of mint tea were sold in the morning.
#### 4.
How many fewer packets of ginger tea than mint tea were sold in total?
- Total Mint sales = 964 packets
- Total Ginger sales = 743 packets
- Difference = Total Mint sales - Total Ginger sales
\[
964 - 743 = 221
\]
-
Answer: 221 fewer packets of ginger tea were sold in total.
#### 5.
How many more packets of mint tea were sold than chamomile tea in the afternoon?
- Afternoon Mint sales = 251 packets
- Afternoon Chamomile sales = 356 packets
- Difference = Afternoon Chamomile sales - Afternoon Mint sales
\[
356 - 251 = 105
\]
-
Answer: 105 more packets of mint tea were sold in the afternoon.
Final Answers:
1. \( \boxed{241} \)
2. \( \boxed{331} \)
3. \( \boxed{432} \)
4. \( \boxed{221} \)
5. \( \boxed{105} \)
