Ivanhoe Co.uses a standard job cost system with a normal capacity of 25.100 direct labour hours. Ivanhoe Co. produces 12,000 units, which cost $207.900 for direct labour (23,100 hours) $24.000 for variable overhead, and $139,200 for fixed overhead. The standard variable overhead per unit is $2 (2 hours at 51 per hour), and the standard fixed overhead per unit is $10.30(2 hours at $5.15 per hour). Calculate the variable overhead spending variance and the variable overhead efficiency variance. Variable overhead spending variance Variable overhead efficiency variance Unfavourable Neither favourable nor unfavourable Favourable
