A) The constant of proportionality for this relationship is...
B) Calculate the cost of 9 oz of broccoli using the constant of proportionality.
C) The cost of 9 oz of broccoli in this proportional relationship is...
D) Explain how to find the constant of proportionality and the cost of 9 oz of broccoli from the table.

Answer 1

The constant of proportionality for the relationship between weight and cost is 0.30. The cost of 9 oz of broccoli can be found by multiplying the weight by the constant of proportionality.

Step-by-step explanation:

The constant of proportionality for this relationship can be found by dividing the cost by the weight.

Let's take one example from the table, where the weight is 7 oz and the cost is $2.10.

Dividing the cost by the weight, we get 2.10/7 = 0.30.

So, the constant of proportionality is 0.30.

To find the cost of 9 oz of broccoli, we can use the constant of proportionality.

Multiply the weight (9 oz) by the constant of proportionality (0.30) to get the cost. 9 * 0.30 = 2.70.

Therefore, the cost of 9 oz of broccoli is $2.70.
