Answer:
Creating the initial budget to save at least $100 by the end of October:
Income:
- Work-study job at the college library: $600 per month
Fixed Expenses:
- Rent: $250 per month
- Bus pass: $40 per month
- Books: $150 (only in September)
Variable Expenses:
- Food
- Clothing
- Discretionary spending
Now, let's consider the flexibility of expenses in case changes happen in September or October:
1. Changes in Expenses in September or October:
The variable expenses of food, clothing, and discretionary spending can be adjusted most easily in response to changes. For example, if unexpected expenses arise, you could reduce discretionary spending by dining out less frequently, or you could cut back on clothing purchases if needed.
2. In Which Month Did You Save More Money:
Saving more money is easier in September due to lower expenses. In this month, you only have the initial fixed expenses (rent and bus pass) and the books expense. After covering these costs, you can save more of your income.
Now, let's adapt the budget to reflect the new factors:
Income (with raise):
- Work-study job at the college library: $650 per month
Fixed Expenses:
- Rent: $250 per month
- Bus pass: $0 (school program covers it)
- Books: $250 (an additional $100 expense in October)
Variable Expenses (adjusted to meet the saving goal):
- Food: You may have to budget more tightly for food.
- Clothing: Consider postponing clothing purchases.
- Discretionary spending: Reduce discretionary spending further to maintain the goal of saving at least $100 by the end of October.
After these changes, in which month had greater fixed expenses, and which variable expenses did you change to maintain your savings goal:
Greater Fixed Expenses:
- After the changes, October had greater fixed expenses due to the additional cost of books, which was $250.
Changed Variable Expenses:
- To maintain the goal of saving at least $100 by the end of October, you would need to reduce variable expenses. For example, you could cut back on discretionary spending, dine out less frequently, and postpone clothing purchases to ensure you have enough to save while meeting your expenses.
