To calculate the percentage of customers who prefer to shop on Friday or Saturday, you need the data from the bar graph indicating the number of customers who prefer each day.
Assuming you have that data, here's how to calculate the percentage:
- Add the number of customers who prefer Friday and the number of customers who prefer Saturday.
- Find the total number of surveyed customers by adding preferences for all days combined (Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, Sunday).
- Divide the sum from step 1 by the total from step 2, and then multiply the result by 100 to convert it to a percentage.
The formula is:
\[ \text{Percentage} = \left( \frac{\text{Number of customers preferring Friday + Number of customers preferring Saturday}}{\text{Total number of surveyed customers}} \right) \times 100 \]
If you provide the specific values from the graph, I can help you calculate the exact percentage.
