Maize Plastics manufactures and sells bottles per day. Fixed Costs are $30,000 and the variable costs for manufacturing 50 bottles are $10,000. Each bottle is sold for $1,000. How would the daily profit be affected if the daily volume of sales drop by 10%? profits are reduced by $4,000 profits are reduced by $1,000 profits are reduced by $5,000 profits are reduced by $6,000 Cost A is a fixed cost, while B is a variable cost. During the current year, the volume of output has decreased. In terms of cost per unit of output, we would expect that: cost A has remained unchanged cost B has decreased cost A has decreased cost B has remained unchanged
