Answer 1

Explanation:

1. Important information: The original balance of the savings account is 400 dollars, x is the number of dollars added, and y is the total balance of the savings account.

2. I need to find: The total balance of the savings account (y).

3. What is the equation: y = 400 + x

4. Is the equation additive or multiplicative: Additive

5. I know my answer is correct because: I can use the equation y = 400 + x to calculate the total balance and then double-check my answer using mental math or by subtracting 400 from the total balance to find the amount added (x).
