Question

One printing machine-printed 1800 books in 60 hours this week. A second printing machine printed for 40 hours this week but printed books at twice the hourly rate of the first machine. How many books did the second machine print this week?

2,400

3,600

1,860

1,200

Answer 1

1800 / 60 = 30
30 = 30 books per hr for first printing machine

30 x 2 = 60

60 x 40 = 2,400
2,400 = books in a week for second printing machine

(Sorry if i typed or showed my work weird, my brain works like this)
