a commpany is conidering whetjre it shud tender for two contracts (C1 andC2) on offer from a government depertment for the supply of certain componets.if tenders are submited, the company will have to provide extra facilities, the cost of which will have to be entirely recoup from the contract revenue. the risk of course is that if the tenders are unsuccesful then the company will have to writ off the cost of these facilities.
the extra facilities necessary to meet the requirements of contract C1 would cost $50,000. these facilities would, however, provide sufficient capacity for the requirements of contract C2 to be met also. in addition the production costs would be $18,000. the corresponding production costs for contract C2 would be $10,000
if a tender is made for contract C2 only, then the necessary extra facilities can be provided at a cost of $24,000. the production costs in this case would be $12,000

Hi, I would like to work out a maths problem, but unfortunately I am appalling at maths. It's not really that difficult but I would like to work it out anyway.

OK, I did a recent Physics Exam and I know that my mark in it is directly proportional to a type of marking code called UMS (Uniform Mark Scale).

I know that I got 47/60 in the exam and that this converts to 93 UMS out of a possible 100 UMS. In a piece of coursework parallel to this exam it is marked out of 50, not out of 60. However, the coursework is still worth 100 UMS which obviously means that each mark is worth more UMS in the coursework compared to the exam.

What I am trying to find out is how much UMS each mark in the coursework is worth, and I have absolutely no idea how to do this, even though it is probably really easy and simple :(
