If you divide 180 by 12 you will get 15 and if you divide 180 by 15 you will get 12 then subtract both products and i t will give you the answer 3

<h2>Answer:</h2>

The time it takes more by a Sure-Fire printer is:

3 minutes.

<h2>Step-by-step explanation:</h2>

Andrew needs to print a document that is 180 pages long.

<u>Sure-Fire printer:</u>

It prints 12 pages per minute.

This means that 12 pages takes 1 minute

1 page will take: 1/12 minutes

and 180 pages will take= (1/12)×180 minutes

i.e.

180 pages will take= 15 minutes

<u>Centroid printer:</u>

It prints 15 pages per minute.

This means that:

15 pages take 1 minute

1 page will take: 1/15 minute

and

180 pages will take: (1/15)×180 minute

i.e.

180 pages will take: 12 minutes.

<em>Hence, the time it is taken more by a Sure-Fire printer to print 180 pages than by Centroid printer is:</em>

<em> 15 minutes-12 minutes= 3 minutes.</em>
