A few that is charged per call.
It’s the constant which means that it isn’t going to change. It can’t be the total cost because there is no equal sign. It can’t be the cost per minute because the x represents the minutes, which means .1 represents the cost. Lastly it cannot be how long the call lasted because m is the minutes which is the length of the call.
