Answer:
the numbers are missing in this question, so I looked for a similar question and found the following:
standard direct labor time spent on each tax return is 4 hours
standard direct labor rate is $16.50 per hour
last month, 3,570 hours of direct labor were used
900 tax returns were prepared
total wages $66,045.
Actual wage rate = total wage expense / actual number of direct labor hours used = $66,045 / 3,570 = $18.50 per hour
