Answer:
The piecewise functions accurately represents charges based on Ben's cell phone plan is :

Explanation:
Let x be the minutes over cell phone
Let f(x) represents the piecewise function that represents the charges based on Ben's cell phone plan.
We are given that Ben has a cell phone plan that provides 200 free minutes each month for a flat rate of $39.
So,

We are also given that For any minutes over 200, Ben is charged $0.35 per minute.
So, Minutes over 200 = x-200

Hence the piecewise functions accurately represents charges based on Ben's cell phone plan is :
