Which of the following describes relevant nonmonetary costs to businesses?

The correct choice identifies relevant nonmonetary costs to businesses as travel and waiting time costs. These costs are often associated with the time and resources expended in processes that do not involve direct monetary transactions but can significantly impact a business's efficiency and productivity.

Travel costs refer to the time and resources spent by employees or managers when traveling for business purposes, which can include trips to meet with suppliers, clients, or for training. This involves not just the expenses related to transportation, but also the opportunity costs associated with the time spent that could have been used for productive work elsewhere.

Waiting time costs occur when employees or customers are in periods of inactivity that could be avoided or reduced through better management or scheduling. This can lead to inefficiencies and lost opportunities. Both travel and waiting time can affect employee morale and overall business performance, emphasizing their importance as relevant nonmonetary costs.

In contrast, employment of additional staff, marketing expenses, and facility maintenance costs are typically classified as direct monetary costs, as they involve clear financial expenditures made by a business. While they are essential for operational considerations, they do not exemplify the nonmonetary costs that impact a business's performance in the same way that time-related factors do.
