C=0.6*n+4 help!!!!!!!!!!!!?

My teacher gave me this formula as a bonus due monday please help. What is the formula showing. What is C. Please help. C= 0.6*n+4. (* =multiply)

C=0.6*n+4 help!!!!!!!!!!!!?
U LIL CHEATER! IM TELLIN MRS. DWYER!
Reply:It would depend on what n is. If you want to solve for n:





c=.6n+4


c-4=.6n


10c-40=6n


(10c-40)/6=n


5/6c - 20/3 = n
Reply:C answer is dependent of the value of n





n = 4





C = 0.6(4) + 4





C = 2.4 + 4





C = 6.4





- - - - - - - -





n = - 4





C = 0.6(- 4) + 4





C = - 2.4 + 4





C = 1.6

Reply:This could be a cost function where C stands for the cost (or price paid for an object), n could stand for the numbers of objects you will purchase and the added 4 on the end could be shipping cost, restocking fee.





So if you buy 10 slugs at .6 each then you will pay $10 ($6 for the slugs and a $4 excise to pay for remating the remaining slugs........)
Reply:4.6n


I am positive
Reply:This formula is a linear equation relating C and n.





C is 60% of n added to 4.





It could mean...





The total cost is 60% of the price plus an additional $4.00





It depends on the context of the situation for the problem. If you are not given any context, then you could create infinitely many scenarios to fit this equation.
Reply:Can you people read? C stands for degrees Celsius (Centigrade is not in use anymore).
Reply:It's an extremely simple and straightforward formula. What is your difficulty?





The formula C = 0.6*n + 4 expresses a very simple linear relationship between the variables ' n ' and ' C.'





In this formula, ' n ' is some "independent variable," while ' C ' is an "output," the result of evaluating the right-hand side of the relationship.





Many meanings could be applied to both ' n' and ' C.' Since even my famous mind-melding technique cannot divine your teacher's intention, I shall invent some meanings.





Suppose that you are extremely young, and that your parents give you a small allowance. They bankroll you with $4 to start with, but then give you a constant additional amount each week. As you can tell from the "bankroll," they are persons of extremely limited means and frugality. They emphasize that they do not want you to spend all your allowance profligately. You promise to spend only EXACTLY 40% of the regular amount you will receive each week, leaving the bankroll untouched.





Suppose that you keep to your promise. Then, at the end of the week in which you will have received a total of $n in weekly amounts so far, your cash on hand (' C ') will be given by:





C = 0.6*n + 4.





I agree that this is a rather contrived example, but you didn't give us much to work with!





Live long and prosper.





POSTSCRIPT: Having now seen your so-called "Additional details,' I very much doubt that there is any extant temperature system in which the temperature C is related to "degrees Fahrenheit," ' n ' by the relationship C=0.6*n+4.





In fact this very information suggests that either you or your teacher are confused. ' C ' is a standard symbol for degrees Centigrade or Celsius. (These are often taken to be the same, but in fact they have a zero point differing by a very small amount, 0.001C, which is generally ignored.)





So, leaving that technical point aside, the relationships between the C scale and the Fahrenheit (' F ') scale are:





C = 5/9 (F - 32) or C = 5/9 F - 17.77... , and in the other direction,





F = 9/5 C + 32.





However, your formula simply does not look like any physically significant formula that I'm aware of.
Reply:You have 2 variables and 1 equation. I'm confused as to what they are looking for. Is C suppose to be a number or an equation? Or are you solving for n?
