Nicolas has 1400 pokemon cards. Of these cards, 40% are water pokemon and 15% are considered rare pokemon, the rest are rock pokemon. How many rock pokemon cards does Nicolas have? (I have completely forgotten this skill)
aight so 40 % of 1400 is 560 , and 15% of 1400 is 210 . add those and you get 770 . so you got 770 water and rare . you subtract that by 1400 and you got 630 !!
