George is starting a new streaming music service. For a monthly fee, you can stream 50 songs. There is an additional charge for each song over 50. In August, Bill was charged $11.22 for 67 songs and in September he was charged $13.50. Write a function for the total charge. What is the monthly membership fee? What is the additional amount charged per song?

  1. c = m if n<50
    c = m + a(n-50) if n>/= 50

    11.22 = m + a (67-50)
    is
    11.22 = m + 17 a

    13.50 = m + a(n -50)
    you have to know n, the number of songs in September.
