Question

A store can sell 400 candy bars per week when the price is $0.50 per candy bar and they can sell 350 candy bars per week when the price is $0.75 per candy bar.  Let q represent the number of candy bars sold per week and let p represent the price of a candy bar in dollars. Find the linear demand function in the form q = mp + b

 
  • A.

    q = 0.005p – 1.5

  • B.

    q = 200p + 300

  • C.

    q = – 0.005p + 2.5

  • D.

    q = – 200p + 500

  • E.

    q = 0.25p + 50
