    substitute in all ur info first:

    c= $9

    then solve it algebraically:

    $9=0.10t+4

    -4 -4

    -----------------

    $5 =0.10t

    ---- -------- = 50 min. I am not 2 sure though <3

    0.10 0.10

    used the boat for (9 -- 4) / 0.10 min = 50 minutes.

    $9 = 0.10t + 4

    0.10t = 5

    t = 50 mins
