Answer:
The optimal number of pizza that Judith should order is 184.
Step-by-step explanation:
Judith is introducing pizza in the cafeteria menu.
She is expecting a weekly demand of 10 pizzas.
The cafeteria is open 45 weeks a year.
The ordering cost of pizza for Judith is $15 and the holding cost is $0.40.
The annual demand for pizza
=
![45\ *\ 10](https://img.qammunity.org/2020/formulas/business/high-school/i0gbcbytfl3htwboqnc7q24nukvgiusamg.png)
= 450
The optimal number of pizza will be the economic order quantity.
Economic order quantity can be defined as the optimal order quantity that a company should make to minimize its total cost of inventory.
Economic order quantity
=
![\sqrt{(2\ *\ Annual\ demand\ *\ order\ cost)/(Holding\ cost) }](https://img.qammunity.org/2020/formulas/business/high-school/nr51w4ucqkm86t5dn37yt9i84akq09nsnm.png)
=
![\sqrt{(2\ *\ 450\ *\ 15)/(0.40) }](https://img.qammunity.org/2020/formulas/business/high-school/cf8y0lhgn1gpmu500vdo6geznridwrfo7z.png)
=
![√(33,750)](https://img.qammunity.org/2020/formulas/business/high-school/f3c0ek7xeu3vv9fraolatc7vg14wpiutmn.png)
= 183.71
So the optimal number of pizza that Judith should order is 184.
