The owner of Kat Motel wants to develop a time standard for the task of cleaning a cat cage. In a preliminary study, she observed one of her workers perform this task six times, with the following results:

$\backslash$table$[[$Observation$,1,2,3,4,5,6],[\backslash$table$[[$Time$],[($seconds$)]],81,146,72,108,100,109]]$

If the employee performance rating is $1\mathrm{.}50,$ what is the standard time for this task with an allowance of $20$ percent of the workday is used? seconds.
