Answer:

The correct answer is:

0.50 (B)

Explanation:

The Lerner index is used by monopolists to measure market/monopolist power, and it is defined as the percent markup of price over marginal cost.

It is given by the formula:

L = \frac{P - MC}{P}\\where:\\L = Lerner\ index\\P = price = \$40\\MC = marginal\ cost = \$20\\\\L = \frac{40\ -\ 20}{40} \\L = \frac{20}{40}\\ L = 0.5

Note: in a perfectly competitive market, L = 0, which makes Price = Marginal cost in the equation above. But in a competitive market, it is always the case that L ≥ 0

bearhunter [10]

Answer:

a. $33,000.

b. $36,000.

Explanation:

Net income is calculated as sales minus cost of goods sold, selling, general and administrative expenses, operating expenses, depreciation, interest, taxes, and other expenses. It is also called net earnings.

Now, Cash accounting recognizes revenue and expenses only when money changes hands, but accrual accounting recognizes revenue when it's earned, and expenses when they're billed (but not paid).

a. 2014 Cash-basis net income:

Primo Industries collected $105,000 from customers in 2019

Primo Industries also paid $72,000 for expenses in 2019

=105,000-72,000

=$33,000

b. 2014 accrual-basis net income.

=(105,000-25000+40000)-(72000-30000+42000)

=120000-84000

=$36,000
