Answer:

  P = 250 +50t

Step-by-step explanation:

We are given two pairs of time and price:

  (t, P) = (0, 250)  and  (5, 500)

We can put these into the 2-point form of the equation for a line:

  y = (y2 -y1)/(x2 -x1)(x -x1) +y1

  P = (500 -250)/(5 -0)(t -0) +250

  P = 250/5t +250

  P = 50t +250 . . . . Madelyin's cost equation
