Question

1. communicate and justify is the relationship between the number of slices of salami in a sandwich and the number of calories proportional? explain. calories in a sandwich

Explanation:

Step1: Calculate the ratio of Calories to slices for each row

For \(1\) slice: \(\frac{66}{1} = 66\)
For \(2\) slices: \(\frac{96}{2}=48\)
For \(3\) slices: \(\frac{126}{3} = 42\)
For \(4\) slices: \(\frac{156}{4}=39\)

Answer:

No, the relationship is not proportional. In a proportional relationship, the ratio of \(y\) (Calories) to \(x\) (slices of salami) should be constant. Here, the ratios \(\frac{66}{1}=66\), \(\frac{96}{2} = 48\), \(\frac{126}{3}=42\), and \(\frac{156}{4}=39\) are not equal. So the number of Calories is not proportional to the number of slices of salami.
