We will use a real-life scenario to demonstrate how to calculate and analyze changes in an account balance over a period of time. Our protagonist, Anna, has $274.00 in her account on Sunday and makes various deposits and purchases throughout the week. We will use a table to track her transactions and calculate her new balance each day.
Transactions Table
| Day | Debit ($) | Credit ($) |
|---|---|---|
| Sun | 274.00 | |
| Mon | 50.00 | |
| Tue | 120.00 | |
| Wed | 75.00 | |
| Thu | 150.00 | |
| Fri | 25.00 | |

Calculating Daily Balances
To calculate Anna's new balance each day, we need to subtract the debit amount from the previous day's balance and add the credit amount.
Sunday
Anna starts with a balance of $274.00.
Monday
Anna makes a debit of $50.00, so her new balance is:
$274.00 - $50.00 = $224.00
Tuesday
Anna makes a credit of $120.00, so her new balance is:
$224.00 + $120.00 = $344.00
Wednesday
Anna makes a debit of $75.00, so her new balance is:
$344.00 - $75.00 = $269.00
Thursday
Anna makes a credit of $150.00, so her new balance is:
$269.00 + $150.00 = $419.00
Friday
Anna makes a debit of $25.00, so her new balance is:
$419.00 - $25.00 = $394.00
Saturday
Anna makes a credit of $100.00, so her new balance is:
$394.00 + $100.00 = $494.00
Conclusion
In this article, we used a table to track Anna's transactions and calculated her new balance each day. We demonstrated how to subtract debit amounts and add credit amounts to calculate the new balance. This type of analysis is essential in real-life scenarios, such as managing personal finances or tracking business expenses.

Anna's Account Balance: A Mathematical Analysis - Q&A =====================================================
Introduction
In our previous article, we explored the concept of account balances and calculated Anna's new balance each day based on her transactions. In this article, we will answer some frequently asked questions (FAQs) related to account balances and mathematical concepts.
Q&A
Q1: What is the initial balance of Anna's account?
A1: The initial balance of Anna's account is $274.00.
Q2: How do you calculate the new balance each day?
A2: To calculate the new balance each day, you need to subtract the debit amount from the previous day's balance and add the credit amount.
Q3: What is the difference between debit and credit?
A3: Debit refers to the amount of money withdrawn from an account, while credit refers to the amount of money added to an account.
Q4: How do you handle multiple transactions in a single day?
A4: To handle multiple transactions in a single day, you need to calculate the new balance after each transaction and then apply the next transaction to the new balance.
Q5: Can you provide an example of how to calculate the new balance with multiple transactions in a single day?
A5: Let's say Anna makes a debit of $50.00 and a credit of $120.00 on the same day. To calculate the new balance, you would first subtract the debit amount from the previous day's balance:
$274.00 - $50.00 = $224.00
Then, you would add the credit amount to the new balance:
$224.00 + $120.00 = $344.00
Q6: How do you calculate the total balance after multiple days?
A6: To calculate the total balance after multiple days, you need to add up all the debit and credit amounts and then apply the final balance to the initial balance.
Q7: Can you provide an example of how to calculate the total balance after multiple days?
A7: Let's say Anna makes the following transactions over 5 days:
| Day | Debit ($) | Credit ($) |
|---|---|---|
| Mon | 50.00 | |
| Tue | 120.00 | |
| Wed | 75.00 | |
| Thu | 150.00 | |
| Fri | 25.00 |
To calculate the total balance, you would first calculate the new balance each day:
- Monday: $274.00 - $50.00 = $224.00
- Tuesday: $224.00 + $120.00 = $344.00
- Wednesday: $344.00 - $75.00 = $269.00
- Thursday: $269.00 + $150.00 = $419.00
- Friday: $419.00 - $25.00 = $394.00
Then, you would add up all the debit and credit amounts:
Debit: $50.00 + $75.00 + $25.00 = $150.00 Credit: $120.00 + $150.00 = $270.00
Finally, you would apply the final balance to the initial balance:
$274.00 + $270.00 = $544.00
Q8: What are some real-world applications of account balances?
A8: Account balances have real-world applications in various fields, including personal finance, business, and accounting.
Q9: Can you provide some examples of how account balances are used in real-world scenarios?
A9: Here are some examples:
- Personal finance: Understanding how to calculate account balances is essential for managing personal finances and making informed decisions about spending and saving.
- Business: Tracking business expenses and calculating account balances is crucial for making informed decisions about investments and resource allocation.
- Accounting: Understanding how to calculate account balances is essential for accounting and bookkeeping tasks.
Q10: What are some common mistakes to avoid when calculating account balances?
A10: Some common mistakes to avoid when calculating account balances include:
- Forgetting to subtract debit amounts from the previous day's balance
- Forgetting to add credit amounts to the previous day's balance
- Not handling multiple transactions in a single day correctly
- Not adding up all the debit and credit amounts correctly
