Answer:
The correct answer is B.
Explanation:
Giving the following information:
Apr. 1: Beginning inventory of 490 units for $2.16
Apr. 20: Purchase 420 units for $2.63
Dunbar sold 570 units of inventory during the month.
Under LIFO (last-in, first-out) method, the ending inventory is integrated by the first units incorporated into inventory.
First, we need to calculate the number of units in inventory:
Ending inventory in units= total units for sale - units sold
Ending inventory in units= (490 + 420) - 570= 340 units
Ending inventory ($)= 340*2.16= $734.4
Answer: a). Spain
b). none
c). 2.4
Explanation: a). Absolute advantage occurs when a country produces more of a good than the other country. In this case, Spain produces 50 units of Tractors while, Bolivia produces only 30 units of Tractors. Thus, Since Spain is producing more it has an absolute advantage in Tractors.
b). Both the countries are producing equal units of Cotton. Thus, we can say that none of them has an absolute advantage in cotton production.
c. Opportunity cost is the cost of the lost alternative. When Spain produces Tractors it is sacrificing production of Cotton. So, opportunity cost on 1 unit of Tractor will be,

Thus, 2.4 units of cotton which is given up is the opportunity cost of Spain for producing 1 unit of Tractor.
Answer: c. earns a higher return than the rate paid on debt.
Explanation:
If the debt that the company incurs leads to the company making more money than they are paying as interest for the debt, then more money will be available as net income which would increase the Return on Equity.
ROE is calculated by dividing the Net Income by Shareholder equity. Interest is an expense. If this expense is lower then the increase in net income as a result of the debt then it follows that net income would increase and so would ROE.
