Aleks [24]

Answer:

a. $9,338

b. 0.363

Explanation:

a. Contribution Margin  = Sales - Variable Cost

Where Sales = $25,700

Variable Cost = Food & Packaging + Payroll + 40% x General, Selling and Administrative expenses

V.C. = 8,982 + 6,500 + 40% * 3,700

V.C = 8,982 + 6,500 + 1,480

= $16,362

Therefore, Contribution Margin  = Sales - Variable Cost  

= $25,700 - $16,362

=$9,338

b. McDonald's contribution margin ratio  = Contribution Margin / Sales

= $9,338 / $25,700

= 0.363

Mrrafil [7]

Explanation:

To understand the basic philosophy behind the four factors of production

Land - Labor - Capital - Entrepreneurship

Lets consider an example:

Someday, just finishing your college, you think of starting a pizza business and you start selling pizza's one day. You might end up making a Pizza brand like Pizza Hut.

Here, in this example, to start your pizza shop, you need a place or area, this is known as Land factor. When you start making pizza, you need someone to work in that shop, (or if you doing it by yourself too) there should be at least some human being doing it, this factor is referred as Labor. To start the pizza shop, you need to buy the equipment, taking a shop on rent, or buying it, renovation of the shop etc. All of these things need, of course, Money, which is referred as Capital here. The idea you going to start this business, the courage to make it, definitely makes you an Entrepreneur, in utilizing all other factors effectively and efficiently. Therefore, this is linkage between these four factors of production, and how they fit together.

vladimir2022 [97]

In the forbes article, kotlikoff explains that saving and investing decisions should be guided by strategies that maximize expected utility.

Saving can mean a variety of things to various people. Some believe that it requires making a bank deposit. Investing in stocks or making contributions to a retirement plan are some more definitions. Conversely, according to economists, saving is the act of using less of a specific amount of resources today in order to consume more later. So, the choice to delay consumption and put that delayed consumption in an asset is what is meant by saving.

Saving is either deferred consumption or revenue that is not spent. Putting money aside in various accounts, such as a savings account, a pension account, an investment fund, or in cash, counts as a saving strategy. In order to save, expenses like recurrent charges must be reduced.

The price of notebooks is $5, and at that price consumers demand 12 notebooks. If the price rises to $7, consumers will decrease
Vitek1552 [10]

Answer:

3

Explanation:

We are asked to use the midpoint formula.

Here, instead of dividing the change in values by the old value as in the normal elasticity calculation, we use the average of the two.

Mathematically:

Price elasticity of demand according to midpoint formula is :

{Q2 - Q1 / (Q2 + Q1) ÷ 2] × 100%} ÷ {[P2 - P1/ (P2 + P1) ÷ 2] × 100}

Price changed from 5 to 7. The midpoint of 5 and 7 is the average = (5+7)/2 = 6

% change in price in this case is (7-5)/6 * 100 = 100/3 = 33.33%

% change in quantity:

We first find the average = (12+4)/2 = 16/2 = 8

% change = (4-12)/8 * 100 = -100%

The elasticity of demand is thus -100/33.33 = 3
