Final answer:
The fixed costs are $1500 and the variable costs are $35 per unit. The total cost to produce 250 units is $10250. The marginal cost to produce the 250th unit is $35 per unit.
Step-by-step explanation:
The fixed costs refer to the costs that do not vary with the quantity of units produced. In this case, the fixed costs are $1500, as stated in the question.
The variable costs, on the other hand, are the costs that increase proportionally with the quantity of units produced. In this case, the variable costs are $35 per unit.
To find the total cost to produce 250 units, we can use the formula C(q) = fixed costs + (variable costs per unit * quantity of units). Substituting the given values, we get C(250) = $1500 + ($35/unit * 250 units) = $10250.
To find the marginal cost to produce the 250th unit, we need to calculate the change in total cost when increasing the quantity from 249 units to 250 units. Since the variable cost per unit is $35, the marginal cost for the 250th unit is also $35.
