Answer:

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

$f(x)= 39, x \leq 200\\f(x)=39 + 0.35(x - 200), x > 200}$

Step-by-step 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, $f(x)= 39, x \leq 200$

We are also given that For any minutes over 200, Ben is charged $0.35 per minute.

So, Minutes over 200 = x-200

$f(x)=39 + 0.35(x - 200), x > 200}$

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

$f(x)= 39, x \leq 200\\f(x)=39 + 0.35(x - 200), x > 200}$
