A Printed Circuit Board $($PCB$)$ machine installs integrated circuits onto a board. Before starting to produce a board, the PCB machine requires a $23-$minute setup. Once in production, the PCB machine requires only $0\mathrm{.}20$ minutes per board.

a$.$ Currently, the PCB machine produces $400$ boards between setups. Given this operating process, what is the capacity of the PCB machine $($in boards per minute$)?$

Note: Do not round intermediate calculations. Round your answer to $2$ decimal places.
