Printer A prints 36 pages every 1.5 minutes. Printer B prints 114 pages every 3 minutes. Printer C prints 115 pages every 5 minutes Which printer prints the fastest?

Printer B

Step-by-step explanation:

If printer A prints 36 pages every 1.5 minutes (90 seconds) we can divide 90 seconds by 36 to determine how long it takes Printer A to print one page. When we do that, we get 2.5 seconds which means it takes Printer A 2.5 seconds to print one page.

If we do the same with Printer B, we can divide 3 minutes (180 seconds) by 114 to get about 1.5 seconds which means it takes Printer B about 1.5 seconds to print one page.

If we do the same with Printer C, we can divide 5 minutes (300 seconds) by 115 to get about 2.6 seconds which means it takes Printer C about 2.6 seconds to print one page.

From this we can determine which printer prints the fastest and our answer will be Printer B.

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0
