Alex73 [517]

Answer:

The system of equations is

$y=0.08x+16$

$y=35$

Step-by-step explanation:

Let

x ----> the number of minutes of calling time

y ----> the monthly cost of the calling plan

we know that

The linear equation in slope intercept form is equal to

$y=mx+b$

where

m is the slope

b is the y-intercept

In this problem

Plan A

$m=0.08\\b=16$

substitute

$y=0.08x+16$ ----> equation A

Plan B

$m=0\\b=35$

substitute

$y=35$ ----> equation B

therefore

The system of equations is

$y=0.08x+16$

$y=35$
