Answer:
$12,240
Step-by-step explanation:
If the deposits are equivalent to the cost of the containers marked up by 25%, the total cost of goods sold is:
![C = (\$102,000)/(1.25)=\$81,600](https://img.qammunity.org/2021/formulas/business/college/5jqz4xoaopbjtqlyejycpci9c4972vbp8i.png)
Since 15% of the containers were not returned, the cost of goods sold relative to this forfeiture is given by the total cost multiplied by the fraction not returned:
![C_(f)=\$81,600*0.15=\$12,240](https://img.qammunity.org/2021/formulas/business/college/1bumb8eg0wd5ir3sh3xnh8p45dzka9qdv3.png)
$12,240 is the cost of goods sold relative to this forfeiture.
