Answer:
$200,000
Explanation:
Using the sales value at split-off approach, the allocated costs are proportional to the percentage of total sales that each product is responsible for generating. The percentage of sales that derive from product A are:
[tex]A = \frac{700,000}{700,000+300,000}= 70\%[/tex]
Therefore, the total joint costs were:
[tex]C = \frac{C_A}{A}\\ C=\frac{140,000}{0.7}\\ C=\$200,000[/tex]
Total joint costs were $200,000.
