Q16.1)
From eq 16.19:
We get cost for size or capacity difference:
C1=Co (L1/L0)
x=Co (1000/100)0.61
In 1985, for purchasing 10 new units, it will not
cost 10 times more due to the economy scale but if purchasing for 22years
later, the cost will increase due to the inflation.
Inflation per year = 5%
Original cost = $35,000
New original cost due to the inflation for 22 years
later = 35,000 (1+0.05)22= $102,384
So, the estimate of the cost is:
C1 = 102,384 (1000/100)0.61 = $ 417,092

Q16.3)
At break-even point, QB, cost using hard
tooling = cost of using soft tooling.
The chief cost elements are:
·
Cost of tooling, CH = $7500 and CS =
$600
·
Cost of tool setup, SH= $60 and SC =
$100. Parts made in batches, b, of 500 units.
·
Cost of making one part, CpH = $0.80 and
CpS = $3.40
So, at break-even point
CH+ (QB/b) SH + CpH
QB = CS + (QB/b) SS + CpS
QB
QB = (CH-CS) / (((SS-SH)/b)
+ (CpS - CpH)) = (7500-600)/ ((100-60)/500) +
(3.4-0.80))=6900/2.68 = 2574
At break-even point, hard tooling approaches become
more effective than soft tooling. So, for 500 units, the best decision is to
use hard tooling.

General and administrative expenses
(G&A)
Plant manager and staff 180,000
Administrative salaries 120,000
Office utilities 10,000
310,000 (3)
Manufacturing cost = (1) + (2) +(3) = 3,890,000 (4)
Sales expense = 100,000 (5)
Total cost = (4)+ (5) =3,990,000 (6)
Profit margin = profit / sales = P/S = 0.15
Sales (S) = Total cost (CT) + Profit (P)
S =CT + P = CT + 0.15S ;
S = CT / 0.85 = 3,990,000/0.85 =
4,694,118
The unit selling price of turbine is $4,694,116/60
units sold = $ 78,235
