Answer:
B. monopoly firms but not for competitive firms.
Explanation:
Marginal revenue can become negative for monopoly firms but not for competitive firms.
A monopolist’s marginal revenue is always less than or equal to the price of the good.
Marginal revenue is the amount of revenue the firm receives for each additional unit of output. It is the difference between total revenue – price times quantity – at the new level of output and total revenue at the previous output (one unit less).
Since the monopolist’s marginal cost curve lies below its demand curve. When a monopoly increases amount sold, it has two effects on total revenue:
– the output effect: More output is sold, so Q is higher.
– the price effect: To sell more, the price must decrease, so P is lower.
For a competitive firm there is no price effect. The competitive firm can sell all it wants at the given price.
So the marginal revenue on a monopolist's additional unit sold is lower than the price, <u>because it gets less revenue for selling additional units.</u>
<u>Marginal revenue can become negative – that is, the total revenue decreases from one output level to the next.

Suppose $250,000 is used to establish an annuity that earns 6%, compounded quarterly, and pays $6000 at the end of each quarter. It will take about 120 quarters until the account balance reaches $0.
Amount invested (Present value) = $250000
Quarterly payment (At the end of each quarter) (P) = $4500
Interest Rate (Quarterly) (r) = 6% /4
= 1.5% = 0.015
A number of quarters (n) = ?
Future value at the end = 0
Present value of Annuity formula:
Present value = P × 
250000 = 4500 × 
250000 = 300000 × 
250000 / 300000 = 
0.83333 = 
n = 120
Hence is shall take 120 Quarters until the account balance is $0.

Answer:
Variable-ratio
Explanation:
A variable-ratio reinforcement schedule occurs when a behavior is reinforced based on a random number of displays. Thus, unlike fixed schedules, asking for dating partners do not always elicit a positive reward - which is why it is categorized as variable; the response can be positive or negative. It is also not an interval-based reinforcement schedule, since it is not based on time period. Variable-ratio schedules fit this behavior since asking someone out can get you a positive response once you tried hard enough or with enough people - but when it would happen, you cannot predict.

During its first year of operations, puffin incorporated reported sales revenue of $388,200 but only collected $308,000 in cash from customers. at the end of the year, accounts receivable equals:$80200.
Annual revenue is the amount of money your business earns from sales in a year. This does not include costs and expenses. To calculate annual sales, multiply the quantity of each product sold by the selling price, then add the annual sales for each product to arrive at the total annual sales.
A legal entity is an entity that exists legally separate from its owners, managers, operators, employees, and agents. Legal entities have the same powers as individuals, including the right to own and dispose of property, the power to sue and be sued, and the power to contract for a profit.
