Question

Paul has two label-printing machines. Each machine can print 30 labels per minute. On day 1, only the first machine was used, and it printed 90 labels. On the following day, the first machine printed for x minutes and the second machine printed for y minutes. Which expression shows the total number of labels printed by both machines during these two days?

120x + 30y
90 + 30x + 30y
30 + 90x + y
90x + 60y

HOPE THIS HELP :D

Answer 2

90+30x+30y. This is because the first day, 90 labels were printed, then you will use 30 times x to find how many minutes. This is the same for 30 times y. Youre trying to figure out how many minutes each machine printed for.
