Helena can buy 2 shirts for $25 or 3 shirts for $36. do these quantities have a proportional relationship? explain. yes; the ratio of cost to shirts is equivalent. yes; the constant of proportionality is 12. yes; the constant of proportionality is 12.5. no; the ratio of cost to shirts is not equivalent.

Respuesta :

The quantities do not have a proportional relationship because the ratio of the cost to shirts is not equivalent.

Are the quantities proportional?

The two quantities would have a proportional relationship if the constant of proportionality are equal. The constant of proportionality would be equivalent to the cost of one shirt.

The equation that can be used to determine the constant of proportionality is:

k = y / x

Where:

  • y = total cost of the shirts
  • x = number of shirts bought

k = 25 / 2

k = 12.60

k = $36 / 3

k = $12

The quantities are not proportional because the constant of proportionality are different.
