Answer: $50400
Explanation:
Based on the information given in the question, it should be noted that Lincoln Company can take full credit due to the fact that the workers work for more than 400 hours
Therefore, the work opportunity credit will be claimed as 40% of the first $6,000 and this will be:
= (40% × $6000) × 21
= $2400 × 21
= $50400
