    math question

    Taken from the Wonderlic test (have to take for a job interview tomorrow) I can get the answer but I'm having a brain fart on how to do it quickly with an Algebraic formula. Anyone taken algebra more recent than 26 years ago remember how to do this? I only have 12 min for 50 questions tomorrow so would rather do a quick formula instead of working it out the long way.

    In printing an article of 48,000 words, a printer decides to use two sizes of type. Using larger type, a printed page contains 1,800 words. Using smaller type, a page contains 2,400 words. The article is allocated 21 full pages in a magazine. How many pages must be in smaller type?

    Answer is 17. But I worked that out the long way. What's the quick formula to get this answer?

    I threw up a little just reading the question.
    Good luck man.

      Big type=B Small type=S
      B=number of big type pages
      S=number of small type pages
      B+S=21 , B=21-S
      1800B+2400S=48000
      1800*(21-S)+2400S=48000
      37800-1800S+2400S=48000
      37800+600S=48000
      600S=48000-37800
      600S=10200
      S=17
      no simple formula with the two variables. Just substitution

            So B=4?

                          This is what I was looking for. Thanks.
