Populations of organisms vary, more offspring are produced than can survive, and the relative frequency of favorable mutations rises with time.

<h3>What is natural selection?</h3>

According to Charles Darwin's theory of evolution, natural selection is the driving force behind evolution. Physical traits vary across individuals within a species. Their varying genes are the reason of this variance. People that have traits that are most compatible with their surroundings are more likely to live, locate food, avoid predators, and be disease-resistant. These people have a higher propensity to reproduce and convey their genes to their offspring. Individuals with inadequate environmental adaptation have a lower chance of surviving and procreating. As a result, the likelihood of their genes being passed on to the following generation is lower. As a result, the species will eventually develop through time if the individuals who are most adapted to their environment survive.

mote1985 [20]

Answer:

net sales for the period by Bear's Retail Store: 11,515.8

Explanation:

From the sales revenues we will subtract the returns and discounts.

sales revenues

           530

        4,900

  <u>      6,900   </u>

       12,330

sales returns

690 (6,900 for 10 items the custoemr returns 1 item)

<u><em>sales discount on Nancy </em></u>

(6,900 - 690) x 2% = 124.2

net sales:  12,330 - 690 returns - 124.2 discount = 11.515,8‬

Consider a two-firm oligopoly facing a market inverse demand curve of P = 100 – 2(q1 + q2), where q1 is the output of Firm 1 and
pickupchik [31]

Answer:

option (2) q1 = 16; q2 = 12

Explanation:

Given:

P = 100 - 2(q1 + q2)

here,

q1 is the output of Firm 1 and q2 is the output of Firm 2

Firm 1's marginal cost = $12

Firm 2's marginal cost = $20

Now,

Profit maximising level of output is attained where the marginal revenue equals the marginal cost

Thus,

for firm 1,

Total revenue, TR = P×Q

TR = (100 - 2q1 - 2q2) × q1

or

TR = 100q1 - 2(q1)² - 2(q1)(q2)

also,

MR = \frac{\delta TR}{\delta Q}

thus,

MR = 100 - 4q1 - 2q2

MC = $12

now

MR = MC

or

100 - 4q1 - 2q2 = 12

or

88 = 4q1 + 2q2

or

q2 = 44 - 2q1        ............... (1)

also,

for firm 2, we have

TR = (100 - 2q1 - 2q2) × q2

or

TR = 100q2 - 2(q1)(q2) - 2(q2)²

and,

MR = \frac{\delta TR}{\delta Q}

or

MR = 100 - 2q1 - 4q2

and

MC = $20

Now,

MR = MC

or

100 - 2q1 - 4q2 = 20

or

80 - 4q2 = 2q1

or

40 - 2q2 = q1        .....................(2)

Now,

substituting the value of q2 from (1), we get

q1 = 40 - 2(44 - 2q1)

or

q1 = 40 - 88 + 4q1

or

3q1 = 48

or

q1 = 16 units

substituting the value of q1 in equation (1) , we get

q2 = 44 - 2 × 16

or

q2 = 12 units

Therefore,

The correct answer is option (2) q1 = 16; q2 = 12
