    i'm not sure if my reasoning is correct, but i think it takes 16 days.

    let a = gardners, let b = trees, let c = days

    14a => 350b => 15c
    a => 350b => 210c
    a => b => 210c/350 = 0.6c
    a => 480b => 0.6c * 480 = 288c
    18a => 480b => 288c/18
    18a => 480b => 16c

    350 Rose trees, 14 gardeners, 15 days.
    350/15 trees were done per day (23 1/3)
    Each gardener therefore does (350/15)/14 a day. So each gardener does 1 2/3 trees a day. See if you can do the rest from here
