Provide an appropriate response.Can you set up a proportion to solve this problem? Alice is 13 years old. Her hair is 16 inches long. How long will her hair be when she is 23 years old?
What will be an ideal response?
You cannot solve this problem using a proportion because the ratio of age to hair length is not constant. She could cut or trim her hair.
