Answer 1

To calculate Brett's account balance after each week, we can start with his initial amount of $140 and subtract $15 for each week.

Here’s how the calculations go:

- **Week 0**:
\( y = 140 \)
Account balance = $140

- **Week 1**:
\( y = 140 - 15(1) = 140 - 15 = 125 \)
Account balance = $125

- **Week 2**:
\( y = 140 - 15(2) = 140 - 30 = 110 \)
Account balance = $110

- **Week 3**:
\( y = 140 - 15(3) = 140 - 45 = 95 \)
Account balance = $95

Now we can fill in the table:

| Number of Weeks, x | Account Balance (Dollars), y |
|---------------------|------------------------------|
| 0 | 140 |
| 1 | 125 |
| 2 | 110 |
| 3 | 95 |
