    Answer an electrician charges a base fee of $75. plus a $50 for each hour of work. The minimum the electrician charges is $175. Create a table that shows the amount the electrician charges for 1,2,3, and 4 hours of work.

    The hourly cost for h hours worked is C(h):
    C(h) = Max(175, 50h + 75)

    1 hour cost:
    C(1) = Max(175, 50(1) + 75)
    C(1) = Max(175, 50 + 75)
    C(1) = Max(175, 125)
    C(1) = 175

    2 hour cost:
    C(2) = Max(175, 50(2) + 75)
    C(2) = Max(175, 100 + 75)
    C(2) = Max(175, 175)
    C(2) = 175

    3 hour cost:
    C(3) = Max(175, 50(3) + 75)
    C(3) = Max(175, 150 + 75)
    C(3) = Max(175, 225)
    C(3) = 225

    4 hour cost:
    C(4) = Max(175, 50(4) + 75)
    C(4) = Max(175, 200 + 75)
    C(4) = Max(175, 275)
    C(4) = 275
