a. V=235 - 6x; $1415
b. V= 6 - 235x; $205
c. V=235 - 6x; $1401
d. V=235 - 6x; $205

Answer 1

205

Explanation:

We start with 235, this will be our y-intercept.

6 Is deducted from our value every visit, making our slope -6.

Put the two into slope intercept form:

`y=235-6x`

To find the value after 5 visits substitute x for 5:

`y=235-6(5)`

Solve

`y=235-6(5)\\y=235-30\\y=205`

Therefore you have 205 left in your account after 5 visits.
