Question

The diagram below shows a proportional relationship between the number of cans of soup and the price.What is the constant of proportionality for this situation?

Explain what this value means in terms of the soup.

Answer 1

The constant of proportion would be the price per can of soup.

Find this by dividing the total cost by the number of cans:

3.75 / 3 = 1.25

6.25 / 5 = 1.25

The constant of proportion is 1.25

each can of soup costs 1.25
