Why labor and management might be at odds and why?
NikAS [45]
The most frequently employed technique of workers was the STRIKE. Withholding labor from management would, in theory, force the company to suffer great enough financial losses that they would agree to worker terms. Strikes have been known in America since the colonial age, but their numbers grew larger in the Gilded Age.

An Uber driver faces costs for driving that include sunk costs like insurance that contribute to the average cost per mile of $.
crimeas [40]

Answer: sunk costs don't increase as driving increases.

Explanation: sunk costs are irrelevant costs because they have already occured in the past and cannot be avoided. Sunk costs thus do not differ between alternatives, and are unavoidable. The calculation for insurance and other sunk costs are likely not based on the amount of rides the Uber picks up, but rather calculated at a constant rate. So regardless of whether or not the rider pays more or less than the $.50 on the insurance, this will not have any effect on the insurance that is constant and has likely already been paid out.

SQC Inc. had sales of $3,000,000, cost of merchandise sold of $2,100,000, and average inventory of $140,000. What is SQC Inc.'s
Goryan [66]

Answer:

Days' sales in inventory = 24 days.

Explanation:

We know,

Days' sales in inventory = 365 ÷ Inventory Turnover

Given,

Inventory Turnover = Cost of goods sold (cost of merchandise sold) ÷ Average inventory

Inventory Turnover = $2,100,000 ÷ $140,000

Inventory Turnover = 15 times

Therefore,

Days' sales in inventory = 365 ÷ 15 times

Hence, Days' sales in inventory = 24.33 days

Days' sales in inventory = 24 days.

Days' sales in inventory indicates that within 24 days, the company can sell the inventory.

Natalka [10]

Answer:

See below

Explanation:

Given the above information, segment margin is computed as shown below.

Segment margin = Net sales - Cost of sales - Fixed cost

Given that;

Net sales = $100,000

Cost of sales = $55,000

Fixed cost = $35,000

Then,

Segment margin = $100,000 - $55,000 - $35,000

Segment margin = $10,000

Therefore, the division's segment margin is $10,000
