1. A manufacturer of baseball bats has a fixed cost of $2,000 for equipment and a constant marginal cost o $4 per bat. With this particular cost structure, we can conclude:

1. that both the average variable cost and the average total cost curves will be u-shaped.
2. that both the average variable cost and the average total cost curves will be horizontal lines
3. that both the average variable cost and the average total cost curves will be vertical lines
4. that the average variable cost curve will be a horizontal line while the average total cost curve will be downward sloping
5. that the average variable cost curve will be downward sloping while the average total cost curve will be a horizontal line.
