To find out how many shoppers were buying food for a week or more, we can use the percentage given in the survey.
Given that 40% of the shoppers were buying food for a week or more, we can calculate the number of shoppers as follows:
Number of shoppers buying food = Total number of shoppers surveyed × Percentage of shoppers buying food
Here, we have:
- Total number of shoppers surveyed = 50
- Percentage of shoppers buying food = 40% = 0.40 (as a decimal)
So the calculation is:
Number of shoppers buying food = 50 × 0.40 = 20
Therefore, 20 shoppers were buying food for a week or more.
