Question

The price elasticity of demand for senior citizens purchasing coffee from McDonald's is −5, while non-senior citizens have a price elasticity of demand equal to −1.25. If it costs McDonald's $0.02 to produce a coffee, the optimal price for a cup of coffee for non-senior citizens and the resultant marginal cost under third-degree price discrimination are:_______.A) $0.004 and $0.02.B) $0.02 and $0.80.C) $0.10 and $0.02.D) $10 and $0.20.

Answer 1

Answer:

$0.10 and $0.02. is correct answer

Explanation:

Given:

Elasticity = - 5

Demand = -1.25

Computation:

-e = p / [p-mc]

5 = p / [p-0.02]

5p - 0.1 = p

p = 0.025

for new senior citizen;

1.25 = p / [p-0.02]

p = 0.1

So,

$0.10 and $0.02. is correct answer
