Answer:

The system of equations is

[tex]y=0.08x+16[/tex]

[tex]y=35[/tex]

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

[tex]y=mx+b[/tex]

where

m is the slope

b is the y-intercept

In this problem

Plan A

[tex]m=0.08\\b=16[/tex]

substitute

[tex]y=0.08x+16[/tex] ----> equation A

Plan B

[tex]m=0\\b=35[/tex]

substitute

[tex]y=35[/tex] ----> equation B

therefore

The system of equations is

[tex]y=0.08x+16[/tex]

[tex]y=35[/tex]
