Answer:
Total hours worked = 17,550 hours
Explanation:
Labour hours efficiency variance = labour efficiency variance/standard labour cost per hour
The hourly standard labour cost = $24
= 1,200/24= 50 hours
Labour variance (in hours) = Actual labour hours - Standard hours for actual units produced
The standard labour hours allowed for the production of 875 cranes is:
= 20 × 875 = 17,500 hours
Let the actual hours be "y"
50 = y - 17500
y = 50 + 17500
y= 17,550 hours
Total hours worked = 17,550 hours
