Question

printer a can print a 300 page document in 10 minutes. printer b can print a 400 page document in 8 minutes. Both printers were run until a total of 1000 pages were printed. How many pages did printer b print?

Answer 1

its would be 800 because because because because because

Answer 2

625 pages

Explanation:

Rate x time of the one printer + the rate x time of the second printer = 1000 pages

t= time

(
`(300)/(10)` )t +(
`(400)/(8)`) t = 1000

30t + 50t = 1000

t(30 + 50) = 1000

80t = 1000 Divide both sides by 80

t = 12.5

It took 12.5 minutes to get this job done with both printers.

Look at printer b

`(400)/(8)` (12.5) = pages

50 x 12.5 = 625 pages
