Answer:

  $97.50

Step-by-step explanation:

To evaluate a function, replace the variable in the function definition with the value you want to evaluate it for.

  f(x) = 0.25x +35 . . . . for x=250

  f(250) = 0.25·250 +35 = 62.50 +35

  f(250) = 97.50

Jeff will pay $97.50 if he uses 250 minutes.
