Calculate the below ratios based on the following data: Printer company produces printers has the following expected costs There are 900 printers expected to be sold at an average selling price of $60 per unit Each printer is expected to use 2.2kg of direct materials at a standard cost of $5 per kg Direct labour is expected to consists of 1.8 hours per printer at a standard cost of $13 per hour Variable overhead is expected to consist of 2.2 machine hours at a rate of $3 per hour What is the expected total standard cost per unit? During the year, 1,000 printers were produced with the following results: Total revenues was 58,000 for the year 21,000kg of materials were used at a total cost of $11,550 1900 labour hours were used at a cost of $26,600 3000 machine hours were used at a total cost of $6,300. Calculate the following ratios: 10.1 materials price variance 10.2 materials quantity variance 10.3 labour rate variance 10.4 labour efficiency variance 10.5 variable overhead spending variance 10.6 variable overhead efficiency variance
