A particular raw material is available to a company at three different prices, depending on the size of the order: Less than 100 pounds $ 25 per pound 100 pounds to 3,999 pounds $ 24 per pound 4,000 pounds or more $ 23 per pound The cost to place an order is $50. Annual demand is 4,400 units. Holding (or carrying) cost is 30 percent of the material price. What is the economic order quantity to buy each time, and its total cost

answer; /// i do believe the correct answer is (30,000);

its high unemployment figures

i just had a test with that question

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.'
