Answer 1

Answer:

205

Step-by-step 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.
