    To earn money for college, Avery works two part-time jobs: A and B. She earns $10 per hour working at job A and $20 per hour working at job B. In one week, Avery earned a total of s dollars for working at the two part-time jobs. The graph above represents all possible combinations of the number of hours Avery could have worked at the two jobs to earn s dollars. What is the value of s ?

    A) 128
    B) 160
    C) 200
    D) 320


    Based on the graph the equation of the line is A / 16 + B / 8 = 1 ⇒ A + 2B = 16 and for an arbitrary value for B = 5 hours,
    A = 16 - 2·5 = 6 Hours
    10A + 20B = s
    10·6 + 20·5 = $160 = s.
