    Answer:

    4.3 coats

    Step-by-step explanation:

    if 1 coat takes 3 1/4 hours (same as 3.25 hours)

    3.25 hours = 1 coat

    14 hours = x coats

    (cross multiply)

    3.25 × x = 14 × 1

    3.25x = 14

    (divide both sides by 3.25)

    x = 4.3

    therefore, 4.3 coats are applied

    hope this helps!
