INTRODUCTION TO MATERIALS MANAGEMENT
CHAPTER 1
ANSWERS TO PROBLEMS
1.1 Sales 100% 100%
Cost of manufacturing 60% 50%
Other costs 30% 90% 30% 80%
Profit (percent of Sales) 10% 20%
Therefore a 10% reduction in the cost of manufacturing would produce a 100% increase
in profit.
1.2 Profit = Sales – (direct costs + overhead)
0.20 = Sales – (0.60 × Sales + 0.30)
Sales = 0.5 = 1.25 = 125%
0.4
To increase profits from 10% to 20% takes a 25% increase in sales but only a 10%
decrease in costs. Good materials management can have a direct impact on profit. Note
the cost of overhead has been left unchanged in this problem.
1.3 a. Weekly cost of goods sold = $12,000,000 = $240,000
50
Value of 8 weeks’ WIP = 8 × $240,000 = $1,920,000
b . Value of 6 weeks’ WIP = 6 × $240,000 = $ 1,440,000
Reduction in WIP = $480,000
1.4 a. Weekly cost of goods sold = $30,000,000 = $600,000
50
Value of 10 weeks’ WIP = 10 × $600,000 = $6,000,000
b . Value of 5 weeks’ WIP = 5 × $600,000 = $3,000,000
Reduction in WIP = $3,000,000
Annual saving = 20% × $3,000,000 = $600,000
1.5 Using $1 million as the units:
As a % of sales
Sales $10.0 100%
Direct material $3.5 35%
Direct labor 2.5 25%
Overhead 3.5 9.5 35% 95%
Profit $.5 5%
3
a. From the above we can say: (in millions or M$)
Sales = direct material + direct labor + overhead + profit (now 1M$)
= .35(sales) + .25(sales) + 3.5 M$+ 1.0 M$
.40 (Sales) = 4.5 M$
Sales = 11.25 M$ = 11.25 × $1,000,000 = $11,250,000
Therefore there must be a $1.25 million increase in sales.
b . To increase profit by $500,000 there must be a $500,000 reduction in cost. Therefore
direct material must be reduced by $500,000. It therefore takes 2 ½ times the sales
dollars to obtain the profit that would be realized in material reductions.
c. As for b. Direct labor would have to be reduced by $500,000.
