RM30,000 =RM24,000(2)Total costs of 5,500 hours:Total variable costs = 5,500 x Rm6 =Rm33,000Total fixed costs = RM24,000Total cost = RM33,000 + RM24,000 =RM57,000(3)If the machine hours increase by 50%,the variable costs will also increase by 50%.(4)Yse,I agree that the fixed cost will remain the same till year 2015 because fixed cost will never change since it is a fixed costs.Exercise 4No.of customer RMhighest 2925 1450Lowest 2400 1200Difference 525 250Variable cost = 525/250 =RM2.10Total variable cost = 2400 x RM2.10 =RM5040 at total cost of RM1200 Total fixed cost = RM1200 -

Problem 4(-)variable cost RM55,000Contribution RM20,000(-)Direct fixed cost RM12,000Profit RM8,000The labour cost that relevant is could be the same with the other work.Case studyA.MCKK Corporation(1)His statement is incorrect because he should consider either to classified as a manufacturing cost or as a selling expenses.The salary will affect the outcome of the launch if it not classified at the right place.If the salary classified as a manufacturing(product) cost,the payment of the salary is based on the outcome of the advertising campaign.Move successful the campaign,more cost incurred to pay the salary.But if the annual salary classified aa selling expense,the company still paid the RM30,8-- because I am not required for manufacturing the advertising campaign.The total amount for period cost remain same for any level of output.(2)Examples of avoidable cost is variable cost.It is relevant cost in decision making because these costs are future cost which have not been incurred.B.(1)Period cost-Advertising fees RM500/month-Cost of goods sold RM5/cake-Legal and filling fees RM200Product cost-Cost of raw material RM25/cake-Phone rental RM95/month(2)The relevabt cost to consider is the cost of manufacturing which is direct material,directlabour and variable overheads,because they have not been incurred and will change the decision.C.Sendiri manufacturing(1) Schedule of cost of goods manufacturedRM RMRMBeginning bal of work in process inventory 31,000Manufacturing cost for the periodDirect materialbeginning balance 12,000(+)Purchase 275,000Raw material available for use 287,000(-)Ending balance 17,900Direct material used 269,100Direct labour cost 115,000MAnufacturing overhead 53,050Total manufacturing cost for the period 537,150total cost to account for 568,150(-)Ending bal work in process inventory 38,000Cost of goods manufactured 530,150Manufacturing overhead = indirect labour cost + (65% x utilities) + Depreciation on sales equipment + (75% x insurance) + (60% x rent on facilities)= RM22,000 + 14,950 + 32,000 + 28,000 + 5,100 + 51,000= RM153,050。
