DIRECT VARIATION

EQUATION:

[tex]c = kn[/tex]

where k is the constant of variation.

  • The statement “c varies directly as n” is the reason why it's a direct variation.
  • If the number of pencils increase then as well as the cost, and if the number of pencils decrease then the cost also decrease.
