Explanation:

Consider the provided information.

Joanne is depositing money into a bank account. After 3 months there is $150 in the account. After 6 months there is $300 in the account.

Rate of change is known as how one quantity change in relation to other.

The rate of change can be calculated as:

`(y_2-y_1)/(x_2-x_1)`

Now use the above formula to calculated the rate of change.

`(300-150)/(6-3)`

`(150)/(3)`

`50`

Hence, the constant rate of change of the account is $50 or Increasing by $50 per month.
