Final answer:
Without specific data on the proportion of non-sales roles within the company, we cannot calculate an exact amount for salaries expenses attributable to non-sales personnel. Estimations could be made if the percentage of non-sales staff was provided, applying it to the estimated $450,000 total salaries figure.
Step-by-step explanation:
To determine the amount of salaries expenses attributable to non-sales personnel, we must consider the overall labor expenses and the proportion of the workforce involved in non-sales activities. As there is no specific data provided for sales versus non-sales personnel, we can use the breakdown of employment categories from Table 6.7 as an approximation. Wages and salaries account for about 75% of total compensation, which implies that non-wage benefits account for about 25% of the total compensation package.
Considering that the firm spent $600,000 on labor overall, we can estimate that $450,000 was spent on wages and salaries (75% of the labor costs), if we ignore the variation in compensation due to factors like experience or education. However, without precise figures on the ratio of sales to non-sales personnel, an exact number for non-sales salaries expenses cannot be provided. If we knew what percentage of the 112.0 million paid employees represented non-sales roles, we could apply that percentage to the $450,000 to estimate the salaries expenses for non-sales staff.
