Judith Thompson, the manager of the student center cafeteria, has added pizza to the menu. The pizza is ordered frozen from a local pizza establishment and baked at the cafeteria. Judith anticipates a weekly demand of 10 pizzas. The cafeteria is open 45 weeks a year, 5 days a week. The ordering cost is $15 and the holding cost is $0.40 per pizza per year. The pizza vendor has a 4-day lead-time and Judith wants to maintain 1 pizza for safety stock. What is the optimal reorder point

9 pizzas

Explanation:

Given that:

A pizza is ordered frozen from a local pizza establishment and baked at the cafeteria.

Judith anticipates a weekly demand of 10 pizzas.

Opening weeks in a year = 45 weeks

Opening days in a week = 5 days

Daily demand =  10/5 = 2

Ordering cost = $15

Holding cost = $0.40 /pizza/year

Lead time = 4 days

Safety stock = 1 pizza

The objective is to determine the optimal reorder point.

The optimal reorder point = (daily demand × lead time) + safety stock

The optimal reorder point =( 2 × 4 ) + 1

The optimal reorder point = 8 + 1

The optimal reorder point = 9 pizzas

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.'
