Alexander is in the business of manufacturing phones. He must pay a daily fixed cost to rent the building and equipment, and also pays a cost per phone produced for materials and labor. Let C represent the total cost, in dollars, of producing pp phones in a given day. A graph of C is shown below. Write an equation for C then state the y-intercept of the graph and determine its interpretation in the context of the problem.



C = [___________]
The y-intercept of the function is [____] which represents
(A: The number of days to produce all of the phones.)
(B: The fixed cost for all rent and equipment.)
(C: The total cost to produce all of the phones.)
(D: The additional cost to produce each phone.)
(E: The number of phones produced in day.)
