Using the concept of proportionality, it is found that these following situations represent proportionality:

A) The total amount a babysitter makes who earns $10 an hour for babysitting r hours.

C) The total amount Andrew saves when he saves $24 a week for w weeks.

In a proportional relationship, the output y is given by the input x multiplied by a constant k, that is:

[tex]y = kx[/tex].

  • Thus, when x = 0, y = 0.

In this problem:

  • In options A and C, when the input is 0, the output is also 0, thus they are proportional.
  • In option B, when the input is 0 days, the output is 5 inches of snow, thus it is not proportional.
  • In option D, when the input is of 0 months, the height is of 7 inches, thus also not proportional.
