Work center A produces parts that are then processed by work center B$.$ Kanban containers used by the work centers hold $110$ parts. The overall rate of demand is $3\mathrm{.}5$ parts per minute at work center B$.$ The table below shows setup, run, move, and wait times for parts at each of the work centers.

What is the minimum number of containers needed between these two work centers?

Two work centres namely A$,$ and B$.$

Setup time for A $=3$

Setup time for B $=4$

Run time $($per part$)$ for A $=0\mathrm{.}2$

Run time $($per part$)$ for B $=0\mathrm{.}3$

Move time for A $=3$

Move time for B $=5$

Wait time for A $=15$

Wait time for B $=5$

Overall rate of Demand $($D$)=3\mathrm{.}5$

Containers used by the work centres hold parts $($C$)=110$
