To complete your checkbook register for your checking account at ReallyBigBank, we will go through each transaction step-by-step, calculate the totals, and maintain a running balance.

### Checkbook Register

| Number | Date | Transaction Description | Payment | Deposit | Balance |
|--------|------------|---------------------------------------------------------|---------|---------|-----------|
| | August 1 | Opened checking account | | $100.00 | $100.00 |
| 101 | August 2 | Purchased groceries from Grocer’s Haven | $43.82 + 4% Tax | | |
| | | Tax = $43.82 * 0.04 = $1.75, Total = $43.82 + $1.75 = $45.57 | $45.57 | | |
| | August 2 | Paid for parking | $8.00 | | |
| 102 | August 4 | Deposited paycheck from work ($9.75/hr * 40 hours) | | $390.00 | |
| | | Total Earned = 9.75 * 40 = $390.00 | | | |
| 103 | August 6 | Paid HydroPower | $35.11 | | |
| | August 6 | Bought pants (3 pairs x $29.99 each) with discount and tax | $29.99*3 = $89.97 | | |
| | | Discount = $89.97 * 0.10 = $8.99 (Total after discount = $89.97 - $8.99 = $80.98) | | |
| | | Tax = $80.98 * 0.05 = $4.05, Total = $80.98 + $4.05 = $85.03 | $85.03 | | |
| 104 | August 7 | Bought a bike, helmet, and gloves | | | |
| | | Bike: $180.00, Helmet: $14.95, Gloves: $8.95 = $203.90 | | | |
| | | Discount = $203.90 * 0.15 = $30.585 (Total after discount = $203.90 - $30.585 = $173.315) | | |
| | | Tax = $173.315 * 0.04 = $6.93, Total = $173.315 + $6.93 = $180.25 | $180.25 | | |
| 105 | August 11 | Deposited paycheck from work less $90 | | $300.00 | |
| | | Total = (390 - 90) = $300.00 | | | |
| | August 11 | Opened savings account with $110.00 | $110.00 | | |
| | August 12 | Lunch at Hamburger Mayvn | $5.65 + 5% Tax | | |
| | | Tax = $5.65 * 0.05 = $0.28, Total = $5.65 + $0.28 = $5.93 | $5.93 | | |

### Process of Completing the Transactions:

1. **Opened Checking Account**:
- Starting balance: $100.00

2. **Purchased Groceries**:
- Tax calculation: $43.82 * 0.04 = $1.75
- Total amount = $43.82 + $1.75 = $45.57
- Update balance: $100 - $45.57 = $54.43

3. **Paid for Parking**:
- Balance after payment: $54.43 - $8.00 = $46.43

4. **Deposited Paycheck**:
- Earnings from work: $9.75 * 40 hours = $390.00
- Update balance: $46.43 + $390.00 = $436.43

5. **Paid HydroPower**:
- Update balance: $436.43 - $35.11 = $401.32

6. **Purchased Pants**:
- Total for pants before tax: $29.99 * 3 = $89.97
- Discount: $89.97 * 0.10 = $8.99
- New total after discount: $89.97 - $8.99 = $80.98
- Sales Tax: $80.98 * 0.05 = $4.05
- Total = $80.98 + $4.05 = $85.03
- Update balance: $401.32 - $85.03 = $316.29

7. **Purchased Items from Wheels-2-Go**:
- Total cost: $180.00 + $14.95 + $8.95 = $203.90
- Discount: $203.90 * 0.15 = $30.585
- New total after discount = $203.90 - $30.585 = $173.315
- Sales Tax: $173.315 * 0.04 = $6.93
- Total = $173.315 + $6.93 = $180.25
- Update balance: $316.29 - $180.25 = $136.04

8. **Deposited Paycheck Less $90**:
- Update balance: $136.04 + $300.00 = $436.04

9. **Opened Savings Account**:
- Withdrawal for savings: $110.00
- Update balance: $436.04 - $110.00 = $326.04

10. **Ordered Lunch at Hamburger Mayvn**:
- Tax calculation: $5.65 * 0.05 = $0.28
- Total amount = $5.65 + $0.28 = $5.93
- Update balance: $326.04 - $5.93 = $320.11

### Final Balance as of August 12:
- The balance in your checking account after all transactions on August 12 is **$320.11**.

### Summary of Equations Used:
1. **Tax**: Amount (before tax) * tax rate
2. **Total**: Amount (before tax) + Tax
3. **New Balance**: Previous Balance +/- Transaction Amount

This contains a careful breakdown of each transaction and details on how to manipulate the figures correctly in your checkbook register.
