worker$-$machine operation was found to involve $4\mathrm{.}3$ minutes of machine time per cycle in the course of $40$ cycles of stopwatch study. he worker's time averaged $2\mathrm{.}8$ minutes per cycle, and the worker was given a rating of $118$ percent $($machine rating is $100$ percent$).$ Midway through the study, the worker took a $10-$minute rest break. Assuming an allowance factor of $18$ percent of work time which is pplied only to the worker element $($not the machine element$),$ determine the standard time for this job. $($Do not round intermediate :alculations. Round your final answer to $2$ decimal places.$)$
