The company uses a standard costing system to assist in the control of costs. According to the standards set for these robes, the factory has a denominator activity level of 780 direct labour-hours each month, which should result in the production of 1,950 robes. The standard costs associated with this level of production are as follows: During April, the factory worked only 760 direct labour-hours and produced 2,000 robes. The following actual costs were recorded during the month: At standard, each robe should require 2.8 metres of material. All of the materials purchased during the month were used in production. At standard, each robe should require 2.8 metres of material. All of the materials purchased during the month were used in production. Required: Compute the following variances for April: 1. The materials price and quantity variances. (Indicate the effect of each variance by selecting "F" for favourable, "U" for unfavourable, and "None" for no effect (i.e., zero variance).) 2. The labour rate and efficiency variances. (Indicate the effect of each variance by selecting "F" for favourable, "U" for unfavourable, and "None" for no effect (i.e., zero variance).) 3. The variable manufacturing overhead spending and efficiency variances. (Indicate the effect of each variance by selecting "F" for favourable, "U" for unfavourable, and "None" for no effect (i.e., zero variance).) 4. The fixed manufacturing overhead budget and volume variances. (Indicate the effect of each variance by selecting "F" for favourable, "U" for unfavourable, and "None" for no effect (i.e., zero variance).)
