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: 11.1 Sales Volume Variance 11.2 Sales Price Variance 11.3 Materials Price Variance 11.4 Materials Quantity Variance 11.5 Labour Rate Variance 11.6 Labour Efficiency Variance 11.7 Variable Overhead Spending Variance 11.8 Variable Overhead Efficiency Variance
