Answer 9

first day : 95 barcodes
second day: 25 barcodes/min * x minutes + 25 barcodes/min * y minutes

Answer 10

wat?

Answer 11

A machine that prints 25 bar codes per minutes prints 25b bar codes in b minutes.
Both machines print at 25 bar codes per minute, so both machines print 25b bar codes in 25 minutes.
On the second day, one machine worked for x minutes and the other one for y minutes.
On the second day, the machines printed 25x + 25y bar codes.
On the first day, 95 bar codes were printed.
Now add the total printing of both days.
What do you get?
