variable costs are dependeing upon production. u re increases production automatically variable cost is also increased.decrease in production means automatically variable cost decreased.
Variable cost or Marginal cost is the cost that is directly proportionate to the number of units being produced (unit being a Tangible item produced or an Intangible service that is provided). It increases proportionately if the number of units that are being produced/provided are increased and decreases proportionately when the number of units that are being produced/provided are decreased.
