A company in the civil engineering industry with headquarters in Johannesburg undertakes contracts anywhere in South Africa. The company has had its tender for a job in the North West Province accepted at R288 000 and work is due to begin in December 2021. However, the company has also been asked to undertake a contract on the south coast of South Africa. The price offered for this contract is R352 000. Both contracts cannot be undertaken simultaneously because of constraints on staff site management personnel and on plant available. An escape clause enables the company to withdraw from the contract in the North West Province, provided notice is given before the end of November 2021 and an agreed penalty of R28 000 is paid. The following estimates have been submitted by the companys quantity surveyor:

Contract price	288 000	352 000

Additional Information:

1. X, Y and Z are three building materials. Material X is not in common use and would not realise much money if re-sold. However, it could be used on other contracts but only as a substitute for another material currently quoted at 10% less than the original cost of X. This also applies to the firm order for Material X. You may assume that it is not possible to cancel the firm order. The price of Y, a material in common use, has doubled since it was purchased; if used, it would definitely have to be replaced at the new price.
2. With the construction industry not yet recovered from the pandemic, the company is confident that manual labour, both skilled and unskilled, could be hired locally on a subcontracting basis to meet the needs of each of the contracts.
3. The plant, which would be needed for the south coast contract, has been owned for some years and R12 800 is the years depreciation on a straight-line basis. If the North West contract is undertaken, less plant will be required but the surplus plant will be hired out for the period of the contract at a rental of R6 000.
4. Salaries and general costs of operating the small headquarters amount to about R108 000 each year. There are usually ten contracts being supervised at the same time.
5. Each of the two contracts is expected to last from March to February, which, coincidentally, is the companys financial year.
6. Site management is performed by permanent employees who are normally based at the company headquarters.
