Final answer:
The constraints necessary to determine the feasible region of the minimization problem have not been provided. Therefore, it is impossible to ascertain which of the given points lies within the feasible region without testing each point against the specified constraints, which are not present.
Step-by-step explanation:
The student's question pertains to identifying which point lies within the feasible region of a minimization problem given certain constraints. However, the constraints necessary to answer this question have not been provided in the question prompt. Therefore, it's not possible to determine which point (A, B, C, or D) is in the feasible region. To establish whether a point is within the feasible region of a system of inequalities, each point must be tested to see if it satisfies all the given inequalities representing the constraints of the problem.
In general, to determine if a point is in the feasible region, you would substitute the x and y values of the point into each inequality. If the point satisfies all the inequalities, then it is in the feasible region. Conversely, if the point does not satisfy even one inequality, it is not in the feasible region. Without the specific constraints, we can't perform this test.
Regarding the demand curve being inelastic, this means that the percentage change in quantity demanded is less than the percentage change in price, which is indicated by an elasticity value less than one. Without more context or a specified range on the curve represented by points D and E, this statement about elasticity alone does not provide information relevant to solving the minimization problem or determining the feasible region.
