The sales price of each furniture is RM150 per unit. The variable cost to produce one furniture is RM100 per unit. Fixed costs for the furniture production is RM50,000. Required: (a) Compute the variable cost ratio and contribution margin ratio. (Two decimal places). (b) Compute the breakeven unit and sales. (c) Calculate the number of furniture kein Company needs to sell in order to achieve a profit of RM200,000 per annum.
