    Exclamation Functions and Graphs !

    Self adhesive label packs are produced with a cost function, C= 3n = 20 dollars and a revenue function, R= 5n + 10 dollars and n is the number of packs produced.
    a) determine the 'break even' production number. check your answer algebraically.

    b) How many self adhesive label packs should be produced to make a profit of $100?

    First off all, I think there is a mistyping.
    It should be C= 3n + 20

    Anyways you can simply take this approach.

    1) For break even

    C = R.
    i.e

    3n + 20 = 5n + 10

    Solve for n.
    n = 5

    2) for profit of $100]
    R - C = 100
    (5n + 10) - (3n + 20) = 100
    Solve for n
    n = 55

    Feel free to ask if you have any further doubts.
