Question

Jeff has two sticker-printing machines. Each machine can print 42 stickers per minute. On day 1, only the first machine was used, and it printed 89 stickers. 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 stickers printed by both machines during these two days? 131x + 42y 42 + 89x + y 89 + 42x + 42y 89x + 84y

Answer 1

89 + 42x + 42y <== ur expression

Answer 2

since each machine can do 42 per minute

1st machine = 42x

2nd machine = 42y

and 89 total were done on the first day the equation is

89+42x+42y
