Answer:
b. set in when the fifth worker is hired
After this point additional worker return will be lower.
Explanation:
Trhe diminishing return are the moment at which the marginal increase in production decrease.
In other words, adding a new resource provide less return than his predecessor.
Marginal
2 do 4 hours
3 do 6 houses (marginal 6 - 4 = 2)
4 do 9 houses (marginal 9 - 6 = 3)
5 do 13 houses (marginal 13 - 9 = 4)
6 do 15 houses (marginal 15 - 13 = 2)
the marginal output decrease from 4 to 2 the returns decreased.

Mr. White was the third and final owner of the talisman in W. W. Jacobs' short story "The Monkey's Paw." He plucked it from the fireplace when the previous owner, Sergeant Major Morris, tossed it there to burn and end the chain of misfortune that came with it. He is motivated mostly by curiosity, since he seems happy with his life and is financially secure.
Mr. White took the paw from his pocket and eyed it dubiously. "I don't know what to wish for, and that's a fact," he said slowly. "It seems to me I've got all I want."

Answer:
coefficient = 0
Explanation:
We have the formula to calculate the price elasticity of demand as following:
<em>Elasticity coefficient = % Change in quantity/ % Change in price</em>
As given:
+) The percentage change in price is: (120-150)/150= - 20%
+) The quantity bought remains unchanged - which means the percentage change in quantity demanded is 0%
=> <em>Elasticity coefficient = % Change in quantity/ % Change in price</em>
<em>= 0/-20 = 0</em>
<em />
<em>So the coefficient of price elasticity of demand in this example would be 0</em>
