Answer:
1) Standard labor hour allowed = 19,700 * 27/60 = 8,865 Hour
2) Standard labor cost allowed = 8,865 * 5.8 = $51,417
3) Labor spending variance = $51,417 - $54,521 = 3,104 U
4) Labor rate variance = (5.8 * 9565 - 54,521) = 956 F
Labor efficiency variance = (8,865 - 9,565) * 5.8 = 4,060 U
5) Variable overhead rate variance = (4.1 * 9,565 - 43,999) = 4,782.5 U
Variable overhead efficiency variance = (8865 - 9565) * 4.1 = 2870 U
