Calculate the below ratios based on the following data: Printer Company produces printers and 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 consist 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 2100kg 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
