How do we determine whether the labor expense is truly larger in a year than that of the previous year? FYI, when the portion of an expense amount over the unit revenues is larger, the expense is considered "truly larger." Group of answer choices If the current year's labor expense amount is larger than that of the previous year, it is truly larger. If the result of "the current year's labor expense divided by the previous year's labor expense" is larger than 100%, then it is truly larger. If the current year's labor expense amount is larger than the budgeted labor expense, this year's labor expense is truly larger. If this year's labor expense percentage (%) over the revenues is larger than that of the previous year, it is considered truly larger
