You are required to determine how much is the cost per unit of each job (30%).

From 1 Jan 20X2, apart from operating on Job order, the management of Sunrise Ltd decided to operate mass production systems on the kitchen cupboards and sell it in three countries. At the end of 20X2, the management of Sunrise Ltd wanted to set the 20X3 budget of Indirect Manufacturing costs that considered to be related with the Direct Labour hours. The production manager has provided 12 months data on those two variables (see below). You are required to prepare the cost function using simple regression analysis (submit the summary output from the excel regression to show your working). You need to use your cost function to predict the increase of Manufacturing Overhead cost for each 100 hours of Direct labour increase within the relevant range. As in 20X3 the management expected an increase of sales that may increase the Manufacturing overhead cost, how much would be the Manufacturing overhead cost for the first quarter (January to March) if the estimated Direct labour hours are 900, 925 and 950 hoursfor January to March respectively (40%).
