Let number of small papers needed = x
Let number of large papers needed = y
Sub for y:
Solving for x gives
Therefore 17 small papers are needed
in printing an article of 24,000 words,a printer decides to usr 2 sizes of type. using a larger type,a printed page contains 900 words.Using a smaller type,a page contains 1200 words. the article is allotted 21 full pages in a magazine.how many pages must be in the smaller type?
Hello,
let x be the number of pages with 900 words per page
let y be the number of pages with 1200 words per page
Then you get a system of simultanous equations:
900x + 1200y = 24000
x + y = 21
Solve for x and y (I don't know which method you prefer, I would use substitution method here)
You should get x = 4 and y = 17
