(e)
Find the break-even point, where the costs are equal in both the systems.
Answer to Problem 14P
Break-even = 5000 maps dispensed per year.
Explanation of Solution
Given information:
Total Cost of System I =
Total Cost of System II =
Break-even point refers to the point where firm earns just zero economic profits. Here, it will be the point where total cost of system I is equal to the total cost of system II.
Calculation:
Break-even point is given by the intersection of the two cost
At break-even,
Total cost of System I = Total cost of System II
Conclusion:
Therefore, for 5 thousand maps dispensed per year the total annual cost of system I and II are equal.
(f)
To determine the range of output at which system I will be considered.
Answer to Problem 14P
Between (0-5000) maps dispensed per year, system I will be recommended.
Explanation of Solution
Given information:
Total Cost of System I =
Total Cost of System II =
System I will be recommended for range of maps between 0-5000 per year. It is between these levels of output that the total cost line of system I is below the total cost line of system II.
Conclusion:
Thus between 0-5000 maps dispensed per year, system I will be less costly.
(g)
To determine the range of output at which system II will be considered.
Answer to Problem 14P
Between (5000-10,000) maps dispensed per year, system II will be recommended.
Explanation of Solution
Given information:
Total Cost of System I =
Total Cost of System II =
System II will be recommended for range of maps between (5000-10,000) per year. It is between this level of output that the total cost line of system I is below the total cost line of system II.
ConclusionThus between (5000-10,000) maps dispensed per year, system II will be less costly.
(h)
Find the average and marginal cost when 3000 maps are dispensed per year.
Answer to Problem 14P
Average cost of System I = 0.0903
Average cost of System II = 0.1016
Marginal cost of system I = 0.90
Marginal cost of system II = 0.10.
Explanation of Solution
Given information:
Total Cost of System I =
Total Cost of System II =
Average cost is also known as the per-unit cost. It can be calculated by dividing total cost by the number of units produced.
Marginal cost is the change in total cost when one more unit of an output is produced. Here.
Calculation:
At 3000 maps dispensed per year,
Total Cost of System I is termed as TC I
Total Cost of System II is termed as TC II
Average Cost of System I is termed as AC I
Average Cost of System II is termed as AC II
Marginal cost is the change in total cost when one more unit of an output is produced. Here, as output increases by 1 units total cost increases by 0.90 for system I and by 0.10 for system II. So, marginal cost for the two systems will be,
Marginal cost of System I is termed as MC I
Marginal cost of System II is termed as MC II
Conclusion:
Average cost of System I = 0.0903
Average cost of System II = 0.1016
Marginal cost of system I = 0.90
Marginal cost of system II = 0.10.

Who got us into this mess? Our investigations will doubtlessly reveal, as they already have, much wishful thinking and miscalculation. They will also find incompetence, predatory behavior and probably some criminality. But let me suggest that, though inevitable and necessary, this exercise is also simplistic and deceptive. -- business It assumes that, absent mistakes and misdeeds, we might remain in a permanent paradise of powerful income and wealth growth.
