According to the given data we have the following:
Each machine can print 44 stickers per minute
So, first machine=44x
second machine=44y
The first machine was used, and it printed 88 stickers on first day.
Therefore, the expression that shows the total number of stickers printed by both machines during these 2 days would be the following:
88 + 44x + 44y
The right answer would be C.
