Evidence
A customer named "John Doe" joined on January 1, 2023.
John Doe made a total of 5 orders.
The total amount spent by John Doe across all orders is $500.
Each order made by John Doe consists of exactly 2 products.
The average price of products in each order is $50.
Question
What is the average price per product that John Doe purchased?
Analysis and Answer
To determine the average price per product that John Doe purchased, we need to break down the information provided and relate it to the database schema.
1. Understanding the Evidence:
John Doe made 5 orders.
Each order consists of exactly 2 products.
The total amount spent by John Doe across all orders is $500.
The average price of products in each order is $50.
2. Calculating Total Products:
Since each order consists of 2 products and there are 5 orders:
\[
\text{Total products} = 5 \text{ orders} \times 2 \text{ products/order} = 10 \text{ products}
\]
3. Calculating Average Price per Product:
The total amount spent is $500, and the total number of products purchased is 10.
\[
\text{Average price per product} = \frac{\text{Total amount spent}}{\text{Total products}} = \frac{500}{10} = 50
\]
Answer
The average price per product from 2018 to 2019 is 20.57%.
Calculation Steps
1. Identify the adjusted operating profit for each year:
2018: €5,216 million
2019: €4,183 million
2. Calculate the absolute change:
\[
\text{Absolute Change} = \text{Value in 2019} \text{Value in 2018} = 4,183 5,216 = 1,033
\]
3. Calculate the percentage change:
\[
\text{Percentage Change} = \left( \frac{1,033}{5,216} \right) \times 100
\]
4. Perform the division and multiplication:
\[
\text{Percentage Change} = \left( \frac{1,033}{5,216} \right) \times 100 \approx 19.77\%
\]
Conclusion
The yearoveryear percentage change in adjusted operating profit from 2018 to 2019 is approximately 19.77%. This indicates a decrease in adjusted operating profit from 2018 to 2019.
