Answer: $4680
Step-by-step explanation:
The joint cost allocated to Preon will be calculated below as:
Preon's value will be:
= 14000 × $6.00
= $84000
Paron's value will be:
= 28000 × $2.00
= $56000
Total value = Preon's value + Paron's value
= $84000 + $56000
= $140000
The joint cost allocated to Preon will be
= 7800 × 84000/140000
= $4680
