Answer:
a. 32 refrigerators
b. 29 refrigerators
Explanation:
a. The computation of the economic order quantity is shown below:
[tex]= \sqrt{\frac{2\times \text{Annual demand}\times \text{Ordering cost}}{\text{Carrying cost}}}[/tex]
[tex]= \sqrt{\frac{2\times \text{500}\times \text{\$100}}{{\$500 \times 20\%}}}[/tex]
= 32 refrigerators
b. Now the reorder point is
= Annual demand ÷ total number of days in a year × lead time + (service level × standard deviation for the lead time)
= 500 units ÷ 365 days × 7 days + (1.90 × 10 units)
= 9.59 + 19
= 29 refrigerators
