Final answer:
To change the budget, remove the bus pass expense, add $100 for books, update monthly income, and review expenses to meet the savings goal.
Step-by-step explanation:
To change the previous budget to reflect the new factors, we need to make adjustments to the income and expenses.
- The school program now covers the expense of the bus pass, so we can remove that cost from the budget.
- We need to add $100 for books in October as an additional expense.
- We need to update the monthly income to $650 due to an unexpected raise at work.
After making these adjustments, we need to ensure that we are still meeting the overall goal of saving $100 by the end of October. We can review the remaining expenses and see if there are any areas we can cut back on to maintain the goal.
