Question

Brent has two barcode printing machines. Each machine can print 25 barcodes per minute. On day 1, only the first machine was used, and it printed 95 barcodes. 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 barcodes printed by both machines during these two days?

Answer 1

I think it would be 95 + 25x + 25y

Answer 2

Answer:

The total number of barcodes printed by both machines during these two days is given by $T=95+25x+25y$

Step-by-step explanation:

Given : Brent has two barcode printing machines. Each machine can print 25 barcodes per minute. On day 1, only the first machine was used, and it printed 95 barcodes. On the following day, the first machine printed for x minutes and the second machine printed for y minutes.  

To find : Which expression shows the total number of barcodes printed by both machines during these two days?        

Solution :

On day 1,

Only the first machine was used, and it printed 95 barcodes.  

So, On 1 day the number of barcodes print = 95      

On day 2,

The first machine printed for x minutes and the second machine printed for y minutes.  

We have given that, Each machine can print 25 barcodes per minute.

In x minutes it print 25x barcodes.

In y minutes it print 25y barcodes.

So, On 2 day the number of barcodes print is $25x+25y$

The total number of barcodes printed by both machines during these two days is given by $T=95+25x+25y$
