In printing an article of 48000 words, a printer is using two sizes of type. Using the larger type, a printed page contains 1800 words. Using smaller type, a page contains 2400 words. The article is allotted 21 full pages in a magazine. How many pages must be in smaller type?
I need to find the equation for this.
Thanks in advance.

Let L be large type page number and let S be small type page number:
eqn 1: L + S = 21 pages
eqn 2: 1800L + 2400S = 48,000 words
Sol'n: From eqn 1, L = 21 - S substitute this to eqn 2...
1800(21-S) + 2400S = 48,000
37,800 - 1800S + 2400S = 48,000
600S = 10,200
S = 17
since S = 17, substitute this to eqn 1... L = 21 - 17 = 4

19 pages of small type if you want to use all 21 pages
19 x 2400 = 45600
1 x 1800 = 1800
1 x 600 = 600
Total = 48000

Um, I don't understand how a different type size can alter the amount of words.. Are you talking about two different articles?
