Answer:
best batch size is 400 units
Step-by-step explanation:
Given data:
Annual demand (D) =1000 units,
Carrying cost (H) = $10 per unit,
set up cost (S)=$400.
model formula is
![Q = \sqrt{(2DS)/(H[1-(d/p)])}](https://img.qammunity.org/2020/formulas/social-studies/high-school/387prg4rykq7dtx8ma17cfm8cldtxpkdsb.png)
d or p for week = 1000/50
=20. p per day
=40 units/7 days.
=5.71
d per day = 20/7
=2.85
![Q = \sqrt{(2* 1000* 400)/(10[1-(2.85/5.71)])}](https://img.qammunity.org/2020/formulas/social-studies/high-school/koxobqof95wakobruei0rp78ai1y4vm42w.png)
on solving we get 400 unit
