Question

Please answer. I've been stuck on this question for a while.

Question: A business purchased a new printer. The number of the pages, y, printed by the new printer in x minutes is represented by the equation y=37x. The number of the pages printed by the OLD printer is represented in the graph below.
Which statements about the printers are true?
Select the TWO correct statements.
​

Answer 1

The new printer prints 100 pages about 4 minutes faster than the old printer

The new printer prints 22 move pages per minute than the old printer

Explanation:

New printer's equation

y = 37x

Old printer's equation

y = 15x

Since the graph is proportional you can take any ordered pair (except (0,0) and put it the form y/x to find the slope. For example, The point (2,30) 30/2 = 15 or the point (4, 60) 60/4 = 15 and so on.

The difference between the rates is 22 pages a minute (37 - 15).

Substituted in 100 for y and solve for x (minutes)

New:

y = 37x

100 = 37x Divide both sides by 37

100/37 =37x/37

3 = x This is rounded

This means that it takes about 3 minutes to print 100 pages.

Old:

y = 15x

100 = 15x Divide both sides by 15

100/15 = 15x/15

7 = x This is rounded

This means that it takes about 7 minutes to print 100 pages.

The new printer can print the same amount of page (100) in 4 less minutes (7-3)
