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 a 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? ___________

Three individuals form a partnership and agree to divide the profits equally. X invests

$9,000, Y invests $7,000, Z invests $4,000. If the profits are $4,800, how much less

does x receive compared to having the profits divided in proportion to the amounts

invested by X, Y, and Z?

S+L=21

S*2400 + L*1800=48000

Is that correct?

Assuming that their profit sharing should be in the same ratio as their investments

X:Y:Z = 9000:7000:4000

= 9:7:4

= 9x:7x:4x

then 9x+7x+4x = 4800

solve for x, and take it from there.
