Please help to solve these problems

1. Two products (W and X) are created from a joint process. Both products can be sold immediately after split-off. There are no opening inventories or work in progress. The following information is available for last period: Total joint production costs $776, 160 Product Production units Sales units Selling price per unit W 12,000 10,000 $10 X 10,000 8,000 $12 Using the sales value method of apportioning joint production costs, what was the value of the closing inventory of product X for last period? 2. WX is reviewing the selling price of one of its products. The current selling price of the product is $25 per unit and annual demand is forecast to be 150,000 units at this price. Market research indicates that the level of demand would be affected by any change in the selling price. Detailed analysis from this research shows that for every $1 increase in selling price, annual demand would reduce by 25,000 units and that for every $1 decrease in selling price, annual demand would increase by 25,000 units. A forecast of the annual costs that would be incurred by WX in respect of this product at differing activity levels is as follows: Annual production (units) 100, 000 160, 000 200, 000 Direct materials $200,000 $320,000 $400, 000 Direct labour $600,000 $960,000 $1, 200, 000 Mixed Overhead (MOH) $880,000 $1,228,000 $1,460,000 Required: a) Calculate the variable overhead (VOH) per unit and the fixed overhead (FOH). MOH = (VOH per unit x annual production) + FOH b) Calculate the total variable cost per unit. c) Calculate the company's profits if the optimum selling price of the product is $22
