Answer:
Silven Industries
If Silven buys its tubes from the outside supplier, it will be able to avoid $1.10 of its own Chap-Off manufacturing costs per box
Explanation:
a) Data and Calculations:
Estimated Production and Sales Units of Chap-Off = 140,000 boxes
Manufacturing cost per box: Avoidable costs
Direct material $ 3.70 $0.74 ($3.70 * 20%)
Direct labor 2.00 0.20 ($2.00 * 10%)
Manufacturing overhead 1.60 0.16 ($1.60 * 10%)
Total cost $ 7.30 $1.10
Outside supplier's price for tubes = $1.20 per box
b) Unless there an alternative use for the machine used in making the tubes internally exists, it may not be cost-effective for Silven to buy from the outside supplier. Alternatively, it should renegotiate a price per box that is less than $1.10 in order to stop making the tubes internally.
