Respuesta :
Printer B prints faster
Solution:
Given that Printer A prints 36 pages every 1.5 minutes
Let "x" be the number of pages printed in 1 minute
Therefore,
1.5 minutes = 36 pages
1 minute = x pages
By cross-multiplication,
[tex]1.5 \times x = 36 \times 1\\\\x = \frac{36}{1.5} = 24[/tex]
Thus unit rate of Printer A is: In 1 minute, Printer A can print 24 pages
Printer B prints 114 pages every 3 minutes
Similarly,
3 minutes = 114 pages
1 minute = x pages
This forms a proportion. Therefore by crossmultiplying we get,
[tex]3 \times x = 114 \times 1\\\\x = \frac{114}{3} = 38[/tex]
Thus unit rate of Printer B is: In 1 minute, Printer B can print 38 pages
Printer C prints 115 pages every 5 minutes
Similarly,
5 minutes = 115 pages
1 minute = x pages
This forms a proportion. Therefore by crossmultiplying we get,
[tex]5 \times x = 1 \times 115\\\\x = \frac{115}{5} = 23[/tex]
Thus unit rate of Printer C is: In 1 minute, Printer C can print 23 pages
unit rate of printer B > unit rate of printer A > unit rate of printer C
On comparing the unit rate of Printer A, B, C we see that, printer B prints faster
Answer:
printer C
Step-by-step explanation:
because if you divide it it will round up
