(a)
How much longer will it take to print the document on a sure-fire printer than on a centroid printer.
(a)
Answer to Problem 6IP
3 minutes
Explanation of Solution
GIVEN:
Andrew needs to print a document that is 180 pages long.
The table shows the speed, in pages per minute (ppm), for three different brands of printer.
Brand | Speed(ppm) |
Apricot | 8 |
Sure-fire | 12 |
Centroid | 15 |
In order find how much longer will it take to print the document on a sure-fire printer than on a centroid printer, using the given table first divide 180 by the printer speed for a centroid printer, than subtract the number of minutes for the centroid printer to print the document from the number of minutes for the sure-fire printer to print the document, to simplify further as shown below:
So, it takes 3 minutes longer to print the document on a sure-fire printer than on a centroid printer.
(b)
How long would it take him to print the same document on a sure-fire printer.
(b)
Answer to Problem 6IP
3minute
Explanation of Solution
GIVEN:
Carlos can print a document on an apricot printer in 4.5 minutes. The table shows the speed, in pages per minute (ppm), for three different brands of printer.
Brand | Speed(ppm) |
Apricot | 8 |
Sure-fire | 12 |
Centroid | 15 |
In order to find how long would it take him to print the same document on a sure-fire printer, using the given table first to find the number of pages in the document, multiply the printer speed of the apricot printer by the number of pages in the document. And to find how long it would take the print the same document on a sure-fire printer, divide the number of pages by the printer speed of thesure-fire printer, to simplify further as shown below:
So, it takes 3minutes to print the same document on a sure-fire printer.
