Let's analyze the budget provided in the table to determine the most serious omission.
1. Cash Inflows:
- Disposable income: [tex]$4,165
- Interest on savings: $[/tex]0
- Income from stocks: [tex]$50
- Total Cash Inflow: $[/tex]4,215
2. Cash Outflows:
- Cash outflows (other expenses): [tex]$60
- Mortgage: $[/tex]373
- Homeowner's Insurance: [tex]$125
- Car payment: $[/tex]200
- Car insurance: [tex]$150
Now let's summarize the given information:
- Total Cash Inflow = $[/tex]4,215
- Total Cash Outflows (sum of the listed amounts) = [tex]$60 + $[/tex]373 + [tex]$125 + $[/tex]200 + [tex]$150 = $[/tex]908
3. Difference between Inflow and Outflow:
- Difference = Total Cash Inflow - Total Cash Outflow = [tex]$4,215 - $[/tex]908 = $3,307
4. Omitted Items:
- The two omitted items in the planning are:
Stock purchases
Life and health insurance
Thus, the most serious omissions in your friend's budget planning are "Stock purchases" and "Life and health insurance." These are significant because they represent important expenditures that should be accounted for in the monthly budget.
