Answer:
a. 26%
b. 28.2%
Explanation:
Consider the following formula:
Gross profit ratio = Net sales - Cost of sales / Net sales
Walgreen's 2015 gross profit ratio: (103444-76520)/103444
26.0%
Walgreen's 2014 gross profit ratio: (76392-54823)/76392
28.2%
Answer:
What is a power grid?
C) Transmission lines and transformers that take and send electricity from generating facilities to end users
Explanation:
A power grid is a system of interconnected transmission lines and transformers that takes electricity from the producers to the consumers. The power grid is very important in the supply of electricity to consumers. Before power is to be transmitted to the consumers, it has to be generated. Traditionally, the conventional way of generating power was from central power stations that utilized sources like; fossil fuels, coal and natural gas. In the recent past, however, more advancements have been made towards more clean energy sources like; wind, geothermal and hydroelectricity. Clean energy sources have several benefits over the traditional sources of energy, like; they don't cause harm to the environment and also they are renewable since they can be used over and over without depletion.
Once the energy has been harnessed and converted to electricity, it needs to be transmitted. The network for transmission to the consumers is what makes up the power grid. Transmission is usually done at very high voltage to minimize losses. However, before providing it the consumers, the electricity needs to be converted to a low voltage by the use of transformers for domestic and commercial consumption.
Answer:
The answer is: B) Market B
Explanation:
Deadweight loss refers to an economic loss caused by market inefficiencies.
Market inefficiencies occur when supply and demand are not in equilibrium. In market A, the tax will barely affect the equilibrium quantity, so the deadweight loss will not be as large as in market B where the equilibrium quantity will be severely affected.
Answer:
The correct answer is option A.
Explanation:
Price elasticity of demand measures the change in the quantity demanded due to a change in the price of the commodity. In order to increase the demand for pizza, Aiyanna decides to lower the price of pizza by 5% per week.
With passage to time, the demand for a commodity becomes more and more elastic. This is because, with time, the consumers are able to get adjusted to price change. So each successive week demand will become more price elastic.
Answer:
a) 3%
b) the new workers contribute 16,068 dollars
c)$160.68 each
d) the old workers contribute 15,000 when they made his contribution
e) rate of return 7.12%
Explanation:
growth rate: the increase in the workforce:
103 new workers / 100 retired - 1 = 0.03 = 3%
103 workers x 1,040 each x 15% = 16,068
assuming no other employee:
$16,068 pension fund / 100 retired persons = 160.68 dollars each
100 workers x 1,000 each x 15% = 15,000
e) the old retire contribute:
1,000 x 15% = 150
they receive 160.68
rate of return:
160.68 / 150 - 1 = <em>0.0712</em>
