What is the constant of proportionality for the relationship between the number of cups of flour and the number of batches of cookies?

A. 0.25
B. 0.5
C. 2
D. 4

No answer is valid, since the question lacks information.

The bot's answer is meaningless.

Thank you Tammy

B. 0.5

To determine the constant of proportionality for the relationship between the number of cups of flour and the number of batches of cookies, we need to have some data points for the relationship. The constant of proportionality is a number that relates the two quantities in a proportional relationship - in this case, the number of cups of flour and the number of batches of cookies.

Let's say we have the following data:

Number of cups of flour: 2, 4, 6, 8
Number of batches of cookies: 1, 2, 3, 4

To find the constant of proportionality, we can take any two corresponding data points and form a ratio:

For example, let's take the first two data points:
1 batch of cookies corresponds to 2 cups of flour.

So, the ratio of the number of cups of flour to the number of batches of cookies is:
2 cups of flour / 1 batch of cookies = 2/1 = 2

This means that for every 2 cups of flour, we have 1 batch of cookies.

Since we need to find the constant of proportionality, we can see that the ratio is 2. This means that the constant of proportionality for this relationship is 2.

Therefore, the answer is C. 2.
