Group of answer choices

Answer 1

see the explanation

Explanation:

Let

x ----> number of usage days

y ---> the total charge monthly in dollars

we know that

The linear equation in slope intercept form is equal to

`y=mx+b`

where

m is the slope or unit rate

b is the y-intercept or initial value

In this problem we have

`m=\$2\ per\ day\ usage`

`b=\$15`

substitute

`y=2x+15`

we have the ordered pair (13,41)

For x=13 usage days

`y=2(13)+15`

`y=\$41`

therefore

That means----> Total charge in one month for 13 days of use is $41
