In printing in article of 48,000 words,a printer decides to use two sizes of type.Using the larger type,a?

Question

printed page contains 1,800 words . Using smaller type ,a page contains 2400 words. the article is alotted 21 full pages in a magazine. How many pages must be in smaller type?

Answer 1

Use the following equations:

total pages = 21 then x+y=21 then y = 21-x

also you have the equation

2400x + 1800y = 48000 (words)

substitute equation 1 into equation 2 and you get:

2400x + 1800(21-x) = 48000

2400x + 37800 - 1800x = 48000

2400x - 1800x = 48000 - 37800

600x = 10200 then x = 17

4 large type pages 17 small type pages.
