Question

Shadow · Answer

So lets try and make sense of this.

Ben has a cell phone plan that provides 200 free minutes each month for a flat rate of $39.

For the functions, x represents the total # of minutes that Ben has taken. 
Therefore, his cost per month should be $39 when x is less than 200.

For any minutes over 200, Ben is charged $0.35 per minute.

This means that when x is greater than 200, Ben is charged $39 plus $0.35 times the # of minutes that he has gone over.

The number of minutes that he has gone over 200 can also be presented by (x - 200).

Because if he went 220 minutes total, 
(220 - 200) = 20minutes

20 minutes over his allowed amount.

Shadow · Answer

Lets take one of my statements.

"Therefore, his cost per month should be $39 when x is less than 200."
Quick edit. His cost will also be 39 when x is equal to 200.

This could be illustrated by:

$$39, x \le 200$$

Shadow · Answer

That basically says, Ben's cost will be 39 when his total minutes taken are less than or equal to 200.
