Two electricians, Electrician A and Electrician B, offer pricing plans for their work. Each electrician charges an initial fee for a service call plus an hourly rate. The charges for each electrician are represented by the equation and the table shown.

Which statement comparing the charges for each electrician is true?

• Electrician A has an initial fee and an hourly rate that are both less than those for Electrician B

• Electrician B has an initial fee and an hourly rate that are both greater than those for Electrician B

• Electrician A has an initial fee that is less than that for Electrician B. The hourly rate for Electrician A is greater than that for Electrician B

• Electrician A has an initial fee that is greater than that for Electrician B. The hourly rate for Electrician A is less than that for Electrician B
