Answer and Explanation:
1. The computation of the joint cost of each production assign to the smooth skin by relative sales values method is shown below:
Smooth skin
= $360,000 × (170,000 × $3.20) ÷ (170,000 × $3.20 + 300,000 × $5.20)
= $360,000 × $544,000 ÷ $2,104,000
= $93,080
And, for silken smooth
= $360,000 × (300,000 × $5.20) ÷ (170,000 × $3.20 + 300,000 × $5.20)
= $360,000 × $1,560,000 ÷ $2,104,000
= $266,920
