Quatro Hermanas is investigating implementing some new production machinery as part of its operations. Three alternatives have been identified, and they have the following fixed and variable cost:

Alternative A) (annual fixed cost: $100,000 annual variable cost per unit:$20.00)

Alternative B) (annual fixed cost: $200,000 annual variable cost per unit:$5.00)

Alternative C) (annual fixed cost: $150,000 annual variable cost per unit:$7.50)

Determine the ranges of production ( units produced per year) over which each alternative would be recommended up to 30,000 units per year
