the cost of electricity (c) varies directly as the number of kilowatt- hour consumption (n)​

Sagot :

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 kilowatt- hour consumption increase as well as the cost of electricity, and if the number of kilowatt- hour consumption decrease then the cost of electricity also decrease.
