A Printed Circuit Board $($PCB$)$ machine installs integrated circuits onto a board. Before starting to produce a board, the PCB machine requires a $4$minute setup. This $4-$minute setup time is fixed and is independent of the number of boards to be produced later. Once in production, the PCB machine processes the boards one by one, and spends $3$ seconds on each board. The batch size the PCB machine uses is $100$ boards$/$batch$.$ The capacity of the PCB machineboards$/$minute$.($Round off your answer to the FIRST decimal point$)$ doffy
