Answer:
The boy: 8 years old
The sister: 11 years old
Explanation:
We assume that the age at present of the boy is x (years old).
As he is younger than his sister 3 years, so that his sister's present age is great than x 3 years
=> Her present age is: x + 3 (years old)
Two years ago, the boy is younger than present two years
=> The boy's age two years ago is: x - 2 (years old)
Similarly, the sister's age two years ago is: (x+3)-2 = x + 1 (years old)
As given, two years ago he was two-thirds of his sister's age, so that we have:
<em>The boy's age two years ago = </em>
<em> × the sister's age two years ago</em>
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
=> x + 3 = 8 + 3 = 11
So the present age of the boy is 8 years old, of the sister is 11 years old
Answer:
the answer is equity.
Explanation:
the social equity in resource allocation and distribution is the main concern of an command economy. The entire "command" function is there for this purpose. Opposing to the market system, in which the efficiency of the market is of primary concern, the command system argues that while following to achieve the maximum market effeciency, these economies miss out on the fainress and unbiasedness in economic benefit destribution and therefore creates many social problems such as poverty, rich and poor gap, etc as a result.
The command economy tries to overcome this problem of Equity in market economies.
Answer:
A price floor set above the equilibrium price will result in a surplus of supply.
Explanation.
An equilibrium price refers to the price at which demand for a service or product is equivalent to the quantity of the product or service supplied in the market.
Setting a price floor above the equilibrium price essentially means that the set prices will be higher than what demand is willing to pay for the product or service. Demand will therefore purchase fewer quantity of the product offered by supply at the prevailing price than they would have at equilibrium price.
Since the price floor will raise the product price to considerably higher than the equilibrium price, supply will be willing to provide higher volumes of the product at the prevailing price than at equilibrium price.
This will lead to a mismatch in the market between supply and demand resulting into a surplus.
Answer:
This project should be rejected because the AAR is 10.68 percent.
Explanation:
The accounting rate of return of the project needs to computed,compared with the required accounting rate of return in order to decide whether the project should accepted or rejected:
Profit margin=$86,800*6%=$5208
Average operating assets=($97,500+$0)/2=$48.750
Accounting rate of return=profit margin/average operating assets*100
Accounting rate of return=$5,208/$48,750*100=10.68%
The project accounting rate of return is lower than the required accounting rate of return,hence the project should be rejected.
