Paul has to label printing machines. each machine can print 30 labels per minute. on day one, 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?

90 + 30x + 30y

Step-by-step explanation:

the machines can print 30 per minute so the amount each printed (x & y)

is 30x & 30y

The total number of labels printed by both machines during these two days is given by

Step-by-step explanation:

Since we have given that

Number of printed labels on the day one by the first machine = 90

Speed of each machine = 30 labels per minute

Let the time taken by the first machine printed be 'x' minutes

Let the time taken by the second machine printed be 'y' minutes.

So, Number of printed labels by first machine on the following day = 30x

Number of printed labels by second machine on the following day = 30y

So, the total number of labels printed by both machines during these two days is given by
