Answer 1

old printers would produce the comic books faster as they are large in number

Explanation:

30 minutes for 5 old printers

18 minutes for 4 new printers

same set of comic books which will produce faster 6 old printers or 2 new printers

let minutes = x

30 minutes for 5 old printers

x minutes for 6 old printers

x/30 = 5/6

x = 5/6 * 30 = 25 minutes

18 minutes for 4 new printers

x minutes for 2 new printers

x/18 = 4/2

x = 4/2 * 18 = 36 minutes

Answer 2

Explanation:

It takes 30 * 5 = 150 old printer minutes per batch

It takes 18 * 4 = 72 new printer minutes per batch

old printers would take 150 old printer minutes / 6 printers = 25 minutes new printers would take 72 new printer minutes / 2 printers = 36 minutes
