Explain how mixed costs are related to both fixed and variable costs. A. Mixed costs have a fixed portion that is a cost per unit of cost driver activity. Mixed costs also have a variable portion that is usually a cost per time period. B. Mixed costs are the sum of the fixed and variable costs that are related to equipment costs. These mixed costs are a form of committed costs during the production phase. C. A mixed cost is the sum of fixed costs and the portion of variable costs that are related to salaries and wages. These mixed costs are discretionary costs that easily fluctuate and must therefore be kept separate during a production phase. D. A mixed cost has a fixed portion that is usually a cost per time period. A mixed cost also has a variable portion that is a cost per unit of cost driver activity.

Answers

Answer 1

Answer:

D. A mixed cost has a fixed portion that is usually a cost per time period. A mixed cost also has a variable portion that is a cost per unit of cost driver activity.

Explanation:

As we know that

The variable cost is the cost that can change when the level of production increase or decrease

The fixed cost is the cost that remains fixed whether the production level increased or not

ANd, the mixed cost includes some part of the variable cost and some part of the fixed cost

So as per the given options, the option D is correct as the mixed cost involved the fixed portion that could be cost per the time. And, it involved the variable portion i.e cost per unit with respect to the cost driver activity

c. will lose their savings because the FDIC only insures business deposite
d. can recover up to $25,000, but they will probably lose the test since the deposits exceed the maximum coverage offered by the FDIC

Answers

Answer:

B

Explanation:

The Federal Deposit  Insurance Corporation (FDIC) was established after the great depression. Bank run was attributed to be one of the causes of the great depression. The FDIC increases confidence of depositors in banks because they insure the deposit of bank customers. In the case a bank fails, customers are assured that they would not lose their monies deposited

The FDIC provides protection for up to $250,000 of deposits

$55,000 is less than $250,000, thus the depositors would receive full protection

Suppose you've just inherited $10,000 from a relative. You're trying to decide whether to put the $10,000 in a non-interest-bearing account so that you can use it whenever you want (that is, hold it as money) or to use it to buy a U.S. Treasury bond.
The opportunity cost of holding the inheritance as money depends on the interest rate on the bond.
For each of the interest rates in the following table, compute the opportunity cost of holding the $10,000 as money.
Interest Rate on Government Bond (Percent) Opportunity Cost (Dollars per year)
8 _____ (10,000.00 / 800.00 / 0.08 / 8.00 / 125,000.00)
10 _____ (10,000.00 / 10.00 / 100,000.00 / 1,000.00 / 0.10)
What does the previous analysis suggest about for money?
a. The quantity of money demanded decreases as the interest rate rises.
b. The quantity of money demanded increases as the interest rate rises.
c. The supply of money is independent of interest rate.

Answers

Answer:

A. $800

B. $1,000

C. a. The quantity of money demanded decreases as the interest rate rises

Explanation:

A. Computation for the opportunity cost of holding the $10,000 as money if Interest Rate is 8%

Opportunity Cost for 8% interest rate=$8%*$10,000

Opportunity Cost for 8% interest rate= $800

Therefore the opportunity cost of holding the $10,000 as money if Interest Rate is 8% will be $800

B. Computation for the opportunity cost of holding the $10,000 as money if Interest Rate is 10%

Opportunity Cost for 10% interest rate =10%*$10,000

Opportunity Cost for 10% interest rate = $1,000

Therefore the opportunity cost of holding the $10,000 as money if Interest Rate is 10% will be $1,000

C. Based on the information given the previous analysis suggest about for money: THE QUANTITY OF MONEY DEMANDED DECREASES AS THE INTEREST RATE RISES.

The second location (B) requires a $200,000 investment and is expected to yield annual net income of $44,000. Compute the return on investment for each Fast & Great Burgers alternative. Using return on investment as your only criterion, which location (A or B) should the company open? (The chain currently generates an 22% return on total assets.)

Effect on net income=$163,800-($20*7,800)

Effect on net income=$163,800-$156,000

Effect on net income= $7,800 Increase

Therefore If the special order is accepted, what will be the effect on net income is $7,800 Increase

The systematic examination of the relationships among selling prices, volume of sales and production, costs, and profits is termed: Group of answer choices contribution margin analysis cost-volume-profit analysis budgetary analysis gross profit analysis

Answers

Answer:

cost-volume-profit analysis

Explanation:

Cost-volume-profit analysis also known as breakeven analysis can be defined as a financial accounting method or technique used for determining the number of units a business firm must sell at a specific price so as to cover all of its costs. It is a concept that allow business owners or financial experts to determine and know what they need to sell either on a monthly or annual (yearly) basis, in order to be able to cover the costs of doing the business.

Basically, it helps us to determine the amount of revenue required for the smooth operation of a business, amount of money needed to cover both fixed and variable costs. Using the breakeven analysis, production costs can be categorized as;

1. Variable costs: these are costs that usually change with respect to changes in the level of production or output. Examples are direct labor, maintenance of equipment or machines, raw materials costs etc.

2. Fixed costs: these are the costs which are not directly related to the level of production or not affected by the quantity of output in an organization. Examples are rent, depreciation, administrative cost, research and development costs, marketing costs etc.

Generally, basic break-even analysis is typically based on the principle that variable costs and revenues generated by a business firm or organization, increase in direct proportion to the volume of production i.e as the volume of production of a business firm increase, its variable cost and revenue generated also increases.

Hence, a cost-volume-profit analysis is mainly used by businesses or organizations to determine how changes in differing levels of activities such as costs and volume affect a company's operating income and net income.
