Final answer:
The relationship between the number of slices of salami and the amount of calories is non-proportional because the ratio of calories per slice changes with each additional slice.
Step-by-step explanation:
The question asks to determine whether the relationship between the number of slices of salami and the amount of calories is proportional or non-proportional. To decide if a relationship is proportional, we check if the ratio of one quantity to the other is consistent across all pairs of data given.
Looking at the slices of salami and their corresponding calories:
To check for proportionality, we can divide the calories by the number of slices to find if the ratio (calories per slice) remains constant:
- 66 calories / 1 slice = 66 calories per slice
- 96 calories / 2 slices = 48 calories per slice
- 126 calories / 3 slices = 42 calories per slice
- 156 calories / 4 slices = 39 calories per slice
Since the ratio changes with each additional slice, we can conclude that the relationship between the number of slices of salami and the amount of calories is non-proportional.
