Brick by Brick (BBB) is a building business that provides a range of building services to the public. Recently they have been asked to quote for garage conversions (GC) and extensions to properties (EX) and have found that they are winning fewer GC contracts than expected.

BBB has a policy to price all jobs at budgeted total cost plus 50%. Overheads are currently absorbed on a labour hour basis. BBB thinks that a switch to activity based costing (ABC) to absorb overheads would reduce the cost associated to GC and hence make them more competitive.

You are provided with the following data:

A typical GC costs $3,500 in materials and takes 300 labour hours to complete. A GC requires only one site visit by a supervisor and needs only one planning document to be raised. The typical EX costs $8,000 in materials and takes 500 hours to complete. An EX requires six site visits and fi ve planning documents. In all cases labour is paid $15 per hour.

Required:

(a) Calculate the cost and quoted price of a GC and of an EX using labour hours to absorb the overheads. (5 marks)

(b) Calculate the cost and the quoted price of a GC and of an EX using ABC to absorb the overheads. (5 marks)

(c) Assuming that the cost of a GC falls by nearly 7% and the price of an EX rises by about 2% as a result of the change to ABC, suggest possible pricing strategies for the two products that BBB sells and suggest two reasons other than high prices for the current poor sales of the GC. (6 marks)

(d) One BBB manager has suggested that only marginal cost should be included in budget cost calculations as this would avoid the need for arbitrary overhead allocations to products. Briefl y discuss this point of view and comment on the implication for the amount of mark-up that would be applied to budget costs when producing quotes for jobs. (4 marks)

Let us consider what science and technology have to contribute to the food problem.

The simplest way to increase food production, one might suppose, is to bring more land 【C1】______ cultivation and put more people to work on it. Some of the underdeveloped countries have resorted to this 【C2】______ approach, without notable success. It contains several fallacies. For one thing, it usually means 【C3】______ into marginal lands where the soil and climatic conditions give a poor 【C4】______ . Cultivation may quickly deplete this soil,【C5】______ it for pasture or forest growth. It is often possible, of course, to turn such lands into useful farms by agricultural 【C6】______ ; for instance, a sophisticated knowledge of how to use the available water【C7】______ an irrigation system may reclaim semi-arid grasslands for crop-growing. But the cultivation of marginal lands i6 in any case unsuccessful【C8】______ it is carried out by farmers with a centuries - old tradition of experience or by modern ex pelts with a detailed knowledge of the【C9】______ conditions and the varieties of crops that are suitable for those conditions. Such knowledge is【C10】______ absent in the underdeveloped countries.

【C11】______ , we know that highly developed countries have not increased the【C12】______ of acres under cultivation, 【C13】______ on the contrary have 【C14】______ their marginal lands and steadily reduced the proportion of the population engaged in farming. Efficient farming【C15】______ concentration on the most efficient lands, and it results in greater production with【C16】______ people. The problem of the underdeveloped countries, then is to increase the【C17】______ of their farms and farmers. This would allow them to industrialize and to feed their people more adequately. It is not easy to【C18】______ , how ever. The farmers are conservative and resistant to change【C19】______ their methods of cultivation. The underdeveloped countries are greatly in need of studies and experiments to help them to【C20】______ modern agricultural methods to their own conditions.

ted because Senator Hart discovered that the boxes of cereals consumed by him, Mrs. Hart, and their children were becoming higher and narrower, with a decline of net weight from 12 to 10.5 ounces, without any reduction in price. There were still twelve biscuits, but they had been reduced in size. Later, the Senator rightly complained of a store-bought pie in a handsomely illustrated hex that pictured, in a single slice, almost as many cherries as there were in the whole pie.

The manufacturer who increases the unit price of his product by changing his package size to lower the quantity delivered can, without undue hardship, put his product into boxes, hags, and tins that will contain even 4-ounce, 8 ounce, one-pound, two-pound quantities of break fast foods, cake mixes, etc. A study of drugstore and supermarket shelves will convince any observer that all possible sizes and shapes of boxes, jars, bottles, and tins are in use at the same time, and, as the package journals show, week by week, there is never any hesitation in introducing a new size and shape of box or bottle when it aids in product differentiation. The producers of packaged products argue strongly against changing sizes of packages to contain even weights and volumes, but no one in the trade comments unfavorably on the huge costs incurred by end less changes of package sizes, materials, shape, art work, and net weights that are used for improving a product's market position.

When a packaging expert explained that he was able to multiply the price of hard sweets by 2.5, from $ 1 to $2.50 by changing to a fancy jar, or that he had made a 5-ounce bottle look as though it held 8 ounces, he was in effect telling the public that packaging can be a very ex pensive luxury, h evidently does come high, when an average family pays about $ 200 a year for bottles, cans, boxes, jars and other containers, most of which can't be used for anything but stuffing the garbage can.

What started the public and Congressional concern about deceptive packaging rumpus'？

A．Consumers' complaints about the changes in package size.

B．Expensive packaging for poor quality products.

C．A senator's discovery of the tricks in packaging.

D．The rise in the unit price for many products.
