Answer:
Option (a) is correct.
Explanation:
Given that,
Purchased jerseys from manufacturers = $150,000
Salary of worker = $40,000
Purchased supplies from an office supply store = $20,000
Sold jerseys = $280,000
Value added at Alejandro's store in 2008:
= Amount for which jerseys sold - Purchased jerseys from manufacturers - Salary of worker - Purchased supplies from an office supply store
= $280,000 - $150,000 - $40,000 - $20,000
= $70,000
