The starting balance of Anna’s account is $1,250. She takes $30 out of her account each month. How much money is in her account after 1, 2, and 3 months? Find an equation to represent the balance in her account at any month.

[list=1] [*]Use the description of the account balance to find the balance after each month. [*]Determine the independent and dependent quantities. [*]Determine if there is a common difference or common ratio that describes the change in the dependent quantity. [*]Use the common difference to write an explicit equation. [*]Evaluate the equation to verify that it is correct. [/list] This applet is provided by Walch Education as supplemental material for the [i]CCGPS Coordinate Algebra[/i] program.
