Respuesta :
The number of books printed by the second machine this week is 750 books.
Since the first printing machine printed 500 books in 40 hours this week, then the hourly rate will be:
= 500/40
= 12.5 books per hour.
Since the second machine printed at twice the hourly rate of the first one, this will be:
= 12.5 × 2 = 25 books per hour
Since the second machine printed for 30 hours, the total books will be:
= 30 × 25
= 750 books.
- Therefore, the number of books printed by the second machine this week is 750 books
