Answer:
$368,000 and $92,000
Step-by-step explanation:
The computation is shown below:
For P-11
= (Sales value of P-11) × (Total joint cost) ÷ (Total sales value)
where,
Total joint cost = $140,000 + $320,000 = $460,000
Total sales value = $672,000 + $168,000 = $840,000
So, the cost for P-11 is
=($672,000) × ($460,000) ÷ ($840,000)
= $368,000
For P-12
= (Sales value of P-11) × (Total joint cost) ÷ (Total sales value)
where,
Total joint cost = $140,000 + $320,000 = $460,000
Total sales value = $672,000 + $168,000 = $840,000
So, the cost for P-11 is
=($168,000) × ($460,000) ÷ ($840,000)
= $92,000
