6. You need to buy some filing cabinets. You know that
Cabinet X costs Rs. 10 per unit, requires six square
feet of floor space, and holds eight cubic feet of files.
Cabinet Y costs Rs. 20 per unit, requires eight
square feet of floor space, and holds twelve cubic
feet of files. You have been given Rs. 140 for this
purchase, though you don't have to spend that
much. The office has room for no more than
72 square feet of cabinets. How many of which
model should you buy, in order to maximize storage
volume?

9. The manufacturer of a certain product is
considering the purchase of one of three different
packaging systems. The product sells for Rs. 10, and

Profit, price for target profit The Martell Company
has recently established operations in a competitive
market. Management has been aggressive in its
attempt to establish a market share. The price of
the product was set at Rs. 5 per unit, well below
that of the company's major competitors. Variable
costs were Rs. 4.50 per unit, and total fixed costs
were Rs. 600,000 during the first year.
Assume that the firm was able to sell 1 million
units in the first year. What was the pretax
profit (loss) for the year?
Assume that the variable cost per unit and
total fixed costs do not increase in the second
year. Management has been successful in
establishing its position in the market. What
price must be set to achieve a pre-tax profit of
Rs. 25,000? Assume that sales remain at
1 million units.
