Question 1108407: In printing an article of 48,000 words, a printer decides to use two sizes of type. Using the larger type, a printed page contains 1,800 words. Using smaller type, a page contains 2,400 words. The article is allotted 21 full pages in a magazine. How many pages must be in smaller type? Answer by ikleyn(52787) (Show Source):
x*2400 + (21-x)*1800 = 48000,
where x = "How many pages must be in smaller type".
Solve for x.
24x + 21*18 - 18x = 480
6x = 480 - 21*18 = 102 ====> x = = 17.
Answer. 17 pages in small font.
