The rate of change is -50 based on the information given.

You would have to substitute the amount of months into the equation for x to properly determine the average rate of change, which is not posted in this question.

Answer:

[tex]-50[/tex]

Step-by-step explanation:

In the [tex]1\text{st}[/tex] month the balance will be [tex]-50(1) +100[/tex] which is [tex]50 [/tex]. In the [tex]2\text{nd}[/tex] month, the balance will be [tex]-50(2) +100[/tex] which is [tex]0 [/tex]. In the [tex]3\text{rd}[/tex] month, the balance will be [tex]-50(3) +100[/tex] which is [tex]-50[/tex].

We can see that for every increase of [tex]1[/tex] month, the balance of the bank account will decrease by [tex]50[/tex].
