Assume the xyz corporation is producing 20 units of output. it is selling this output in a purely competitive market at $10 per unit. its total fixed costs are $100 and its average variable cost is $3 at 20 units of output. what is the economic profit of this corporation?

Economic profit  = $40

Explanation:

given data

producing = 20 units

selling = $10 per unit

total fixed costs = $100

average variable cost = $3

output = 20 units

to find out

economic profit of this corporation

solution

we get here revenue that is express as

revenue = 20 units × $10

revenue = $200

and

now we get variable cost is here as

variable cost = 20 units × $3

variable cost = $60

and

now we get here total cost that is express as

total cost = Fixed cost + Variable cost     1

total cost = $100 + $60

total cost = $160

so now Economic profit will be

Economic profit =  Revenue - Total cost    2

Economic profit = $200 - $160

Economic profit  = $40

ans.

heterothermic organisms include those organisms that can switch between homeothermic (having body temperature higher than environment) and poikilothermic (having variation in internal body temperature) strategies.

some migratory birds show heterothermy as they decrease their metabolic rate during cold nights to keep their body temperature low. drop in metabolic rate allows increase in production efficiency of birds that reduces the internal body temperature to make it equal to external cold temperature during cold nights.

thus, the correct answer is 'birds allow their temperature drop in order to increase their production efficiency.'

b. take periodic breaks and alternate between tasks.  

will increase work efficiency, and avoid health issues.
