Answer:
-0.10
Explanation:
To calculate this, we us the formula for calculating elasticity of demand (E) relevant for the demand equation as follow:
E = (P / Q) * (dQ / dP) .............................. (1)
Where,
Q = 30
P = 90
E = -0.3
dQ / dP = b = ?
We then substitute all the value into equation (1) and have:
-0.3 = (90 / 30) * b
-0.3 = 3 * b
b = -0.3 /3
b = -0.10
Therefore, appropriate value for the price coefficient (b) in a linear demand function Q is -0.10.
NB:
Although this not part of the question, but note that how the linear demand function will look can be obtained by first solving for the constant term (a) as follows:
Q = a - 0.10P
Substituting for Q and P, we can solve for a as follows:
30 = a – (0.1 * 90)
30 = a – 9
a = 30 + 9 = 39
Therefore, the linear demand equation can be stated as follows:
Q = 39 – 0.1P
Let's assume that Atlantis has 140 million adult residents. If there are 90 million employed people and 10 million unemployed people, that leaves 40 million people out of the labor force.
What does the term "labor force" mean?
All people who meet the criteria for inclusion among the employed or unemployed make up the labor force, also known as the population that is currently engaged in labor-force activities. The term "employed" refers to people who work for pay or profit at least one hour per week or who hold a job but are momentarily off the clock due to illness, vacation, or a strike. The armed forces include anyone who served in the armed forces during the time in question, whether they were stationed in the metropolitan territory or elsewhere, and was selected from the pool of all workers available.

Answer: The correct answer is option B; Add D2 to the right of D, showing an increase in demand and increase in equilibrium price.
Explanation: The demand for a commodity is usually affected either positively or negatively by some factors or determinants. Foremost among the factors of demand is price of the commodity. Other factors include;
(a) Price of substitute commodities
(b) Consumers preferences
(c) Population
(d) Weather conditions
(e) Advertising
In the question above, the use of a popular actor as the spokesperson of the product is a form of advertising that is intended to improve upon the perception of the commodity and hence encourage consumers to buy more of it. If the popular personality endorses a product, there is an almost one hundred percent likelihood that consumers would see the product as a preferred choice and this would cause the demand to go up or increase.
An increase in the market demand would be signified by the outward shift of the demand curve to the right from D to D2. Since the x-axis shows the quantity demanded increasing towards the right hand side, then an increase in market demand would be reflected by a shift of the demand curve to the right.
As a result of that, the price would now move from P to P2 which shows an increase in equilibrium price. Also the quantity demanded would move from Q to Q2 which also indicates an increase in demand.
