Answer:
25th house's Marginal cost is $250,000.
Explanation:
Given:
Total cost of 24 houses = $4,800,000
Total cost of 25 houses = $5,050,000
Marginal cost = ?
Computation of marginal cost:
Marginal cost = Change in total cost
Marginal cost = Total cost of 25 houses - Total cost of 24 houses
Marginal cost = $5,050,000 - $4,800,000
Marginal cost = $250,000
So, we say that 25th house's marginal cost will be $250,000 .
