Bill and Ted went into the forest to gather some wild mushrooms. Bill gathered 12 red mushrooms and 6 brown mushrooms.  Ted gathered 14 green mushrooms and 6 blue mushrooms.  If half of the blue mushrooms, two-thirds of the red mushrooms, and all of the brown mushrooms have white spots, how many white-spotted mushrooms did they gather?
Of the 12 red mushrooms, 2/3 had spots, for a total of (2/3)*12=8 white-spotted mushrooms.
Of the 6 brown mushrooms, 100% had spots, for a total of (100/100)*6=6 white-spotted mushrooms.
Of the 14 green mushrooms, 0% had white spots, for a total of 14*0=0 white-spotted mushrooms.
And of the 6 blue mushrooms, half had spots, for a total of (1/2)*6=3 white-spotted mushrooms.
In total, they gathered 8+6+0+3=17 white-spotted mushrooms.
