Final answer:
Tayts Inc.'s variable cost per ladder will remain at $8 per unit, and the total fixed costs will stay at $200,000 when production increases, provided the production increase stays within the relevant range.
Step-by-step explanation:
When Tayts Inc. increases its production of ladders but remains within the relevant range, the company can expect certain behaviors in its costs. Variable costs per unit are costs that vary with the level of output; they are typically constant on a per-unit basis. In this case, the variable cost per ladder is $8 and would remain at $8 per unit even if production increases, assuming that there are no changes in variable costs per unit due to economies of scale or purchasing discounts.
Fixed costs, on the other hand, do not change with the level of output in the short term. Therefore, the total fixed costs of $200,000 would remain the same even if production is increased, because they are not dependent on the number of units produced.
