    Answer:  the 12th graders get 150 bottles

    how did i get 150?:

    we know the total amount is 1,000 bottles of water

    since 9th graders got 1/4 of the bottles. 1/4 of 1,000 is 250

    10th graders: 1/5 of 1,000 is 200

    11th graders: 2/5 of 1,000 is 400

    now we ADD all of the sums together: 250+200+400 (doesnt matter which order but do go in order to not confuse yourself) the total should be 850.

    FINALLY we subtract 1,000 – 850 = 150 bottles that are left for the 12th graders.
