Question

Silven Industries, which manufactures and sells a highly successful line of summer lotions and insect repellents, has decided to diversify in order to stabilize sales throughout the year. A natural area for the company to consider is the production of winter lotions and creams to prevent dry and chapped skin.

After considerable research, a winter products line has been developed. However, Silven’s president has decided to introduce only one of the new products for this coming winter. If the product is a success, further expansion in future years will be initiated.

The product selected (called Chap-Off) is a lip balm that will be sold in a lipstick-type tube. The product will be sold to wholesalers in boxes of 16 tubes for $6.90 per box. Because of excess capacity, no additional fixed manufacturing overhead costs will be incurred to produce the product. However, a $100,000 charge for fixed manufacturing overhead will be absorbed by the product under the company’s absorption costing system.

Using the estimated sales and production of 100,000 boxes of Chap-Off, the Accounting Department has developed the following cost per box:

Direct materials	$	2.60
Direct labor		1.00
Manufacturing overhead		1.80
Total cost	$	5.40
The costs above include costs for producing both the lip balm and the tube that contains it. As an alternative to making the tubes, Silven has approached a supplier to discuss the possibility of purchasing the tubes for Chap-Off. The purchase price of the empty tubes from the supplier would be $0.80 per box of 16 tubes. If Silven Industries accepts the purchase proposal, direct labor and variable manufacturing overhead costs per box of Chap-Off would be reduced by 10% and direct materials costs would be reduced by 20%.
2. What would be the maximum purchase price acceptable to Silven Industries? (Do not round intermediate calculations. Round your answer to 2 decimal places.) maximum purchase price: (per box of tubes)       3. Instead of sales of 100,000 boxes, revised estimates show a sales volume of 115,000 boxes. At this new volume, additional equipment must be acquired to manufacture the tubes at an annual rental of $22,000. Assume that the outside supplier will not accept an order for less than 115,000 boxes. a. Calculate the total relevant cost of making 115,000 boxes and total relevant cost of buying 115,000 boxes . (Do not round intermediate calculations.) Making Buying Total Cost:

Answer 1

Solution 2:

Total manufacturing overhead per unit at 100000 boxes = $1.80 per unit

Fixed manufacturing overhead per unit = $100,000 / 100000 = $1 per unit

Variable manufacturing overhead per unit = $1.80 - $1 = $0.80 per unit

Maximum Purchase price per box acceptable to Silven Industries = reduction in Chap- off manufacturing cost per box if tubes purchased from outside vendor.

Therefore Reduction in Chap-Off manufacturing costs per box = (Direct labor cost per unit + Variable manufacturing overhead per unit) * 10% + Direct material cost per unit * 20%

= ($1 + $0.80)*10% + ($2.60*20%) = $0.70 per box

Hence, maximum purchase price per box = $0.70

Solution 3-a:

Total Relevant cost of making 115,000 boxes = 115,000* Reduction in Chap-Off manufacturing costs per box if purchased from outside vendor + Rent of additional equipment

= 115,000 * $0.70 + 22000= $102,500

Total Relevant cost of buying 115000 boxes = purchase cost = 115,000*0.80  

= $92,000
