A company specialising in the provision of telephone systems for commercial clients. There are two parts to the business: - installing telephone systems in businesses, either first time installations or replacement installations; - supporting the telephone systems with annually renewable maintenance contracts. T Co has been approached by a potential customer, Push Co, who wants to install a telephone system in new offices it is opening. Whilst the job is not a particularly large one, T Co is hopeful of future business in the form of replacement systems and support contracts for Push Co. T Co is therefore keen to quote a competitive price for the job.

The following information should be considered: 1. One of the company's salesmen has already been to visit Push Co, to give them a demonstration of the new system, together with a complimentary lunch, the costs of which totalled 400. 2. The installation is expected to take one week to complete and would require three engineers, each of whom is paid a monthly salary of 4,000. The engineers have just had their annually renewable contract renewed with T Co. One of the three engineers has spare capacity to complete the work, but the other two would have to be moved from contract X in order to complete this one. Contract X generates a contribution of $5 per engineer hour. There are no other engineers available to continue with Contract X if these two engineers are taken off the job. It would mean that T Co would miss its contractual completion deadline on Contract X by one week.

As a result,T Co would have to pay a one-off penalty of 500. Since there is no other work scheduled for their engineers in one week's time, it will not be a problem for them to complete Contract X at this point. 3. T Co's technical advisor would also need to dedicate eight hours of his time to the job. He is working at full capacity, so he would have to work overtime in order to do this. He is paid an hourly rate of 40 and is paid for all overtime at a premium of 50% above his usual hourly rate. 4. Two visits would need to be made by the site inspector to approve the completed work. He is an independent contractor who is not employed by T Co, and charges Push Co directly for the work. His cost is 200 for each visit made. 5. T Co's system trainer would need to spend one day at Push Co delivering training. He is paid a monthly salary of 1,500 but also receives commission of $125 for each day spent delivering training at a client's site. 6. 120 telephone handsets would need to be supplied to Push Co. The current cost of these is 18

20 each, although T Co already has 80 handsets in inventory. These were bought at a price of 16•80 each. The handsets are the most popular model on the market and frequently requested by T Co's customers. 7. Push Co would also need a computerised control system called ‘Swipe 2'. The current market price of Swipe 2 is 10,800, although T Co has an older version of the system, ‘Swipe 1', in inventory, which could be modified at a cost of 4,600. T Co paid $5,400 for Swipe 1 when it ordered it in error two months ago and has no other use for it. The current market price of Swipe 1 is 5,450, although if T Co tried to sell the one they have, it would be deemed to be ‘used' and therefore only worth 3,000. 8. 1,000 metres of cable would be required to wire up the system. The cable is used frequently by T Co and it has 200 metres in inventory, which cost 1

•20 per metre. The current market price for the cable is 1•30 per metre. 9. You should assume that there are four weeks in each month and that the standard working week is 40 hours long.
