The following is the description of a cost: Total fixed costs are $5,450 per month, and the variable cost per unit is $9.00 when production is under 300 units. The variable cost drops to $8.00 per unit after the first 300 units are produced. (a) Write the algebraic expression of the cost function. Cost Formula: Total Cost = 5450 9 to + x Quantity, for Quantity s 300 5150 + $ 8 x Quantity, for Quantity > 300
