a. 32 refrigerators

b. 29 refrigerators

Explanation:

a. The computation of the economic order quantity is shown below:

$= \sqrt{\frac{2\times \text{Annual demand}\times \text{Ordering cost}}{\text{Carrying cost}}}$

$= \sqrt{\frac{2\times \text{500}\times \text{\$100}}{{\$500 \times 20\%}}}$

= 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
