If a firm's variable cost per unit estimate used in its base case analysis is $50 per unit and they anticipate the upper and lower bounds to be /- 10%, What is the "worst case" for variable cost per unit

$55

Explanation:

Variable cost of production is the portion of production cost that varies with production amount. In addition to fixed cost it gives total cost of production.

Since there is a +-10% boundary for variable cost. The worst case in terms of high variable cost is 100%+10%= 110%

So worst price = 1.10* 50= $55

On the other hand best case scenario is 100-10= 90%

Best price= 0.9* 50= $45

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.'
