    B = number of books to print via process 1.

    A = number of books to print via process 2.

    P Break point where total cost is same for both processes.

    Process 1:

    210 + 5.69B = Total cost.

    Process 2:

    350 + 5.31A = Total Cost

    ============================

    210 + 5.69P = 350 + 5.31P

    5.69P - 5.31P = 140

    .38P = 140

    P=368

    Check

    350 + 5.31A = Total Cost

    350 + 5.31* 368 = 2304.08

    210 + 5.69B = Total Cost

    210 + 5.69* 368 =2303.92

    So if you print more that 368 books use process 2 if less that 368 use process one.
