An unfavorable flexible budget variance for direct labor is found to be $$3\mathrm{.}50$ per unit of output. This variance means,Group of answer choicesThe actual direct labor cost per output unit is $$3\mathrm{.}50$ higher than the standard costs per output unit.The actual time used to produce an output unit exceeds the standard time and hence, resulted an additional cost of $$3\mathrm{.}50$ per output unit.All of the answer choices are correct.The actual direct labor rate per hour is $$3\mathrm{.}50$ higher than the standard direct labor rate.
