    Answer: see below
    Step-by-step explanation:
    The charges is always at least $80 just for the plumber to show up. The, it increases by $60/hour.
    We represent cost, c in dollars, as below.
    part A –>  c = 80 + 60h
    where h is the number of hours.
    For 3 hours work, c = 80 + 60(3) = 80 + 180 = $260
    part B –>  $260
    I hope this helps.
