Answer:
option (D) $1,000
Explanation:
Data provided in the question:
Sales when 10 prefabricated garages per week are sold = $10,000 each
Sales when 9 prefabricated garages per week are sold = $11,000 each
Now,
Marginal revenue is given as Change in revenue with 1 unit change in production
Thus,
Marginal revenue = ( $10,000 × 10 ) - ( $11,000 × 9 )
= $100,000 - $99,000
= $1,000
Hence,
The answer is option (D) $1,000
