Is Yoli's budget feasible for a month, assuming a month is 30 days? How do you know?

1. Write down the total expected expenses for one day. Let this amount be \[ D. \] 2. Multiply the daily expense by 30 (since a month is taken as 30 days) to get the cost of variable daily expenses over the month: \[ \text{Variable Monthly Expense} = 30 \times D. \] 3. If Yoli also has fixed monthly expenses (for example, rent, subscriptions, etc.), denote their total by \[ F. \] 4. Then the total monthly expenses become \[ E = 30 \times D + F. \] 5. Let Yoli’s monthly income be denoted by \[ I. \] 6. The budget is feasible if the total monthly expenses do not exceed the monthly income, meaning the following inequality must hold: \[ 30 \times D + F \leq I. \] 7. To decide whether the budget is feasible, substitute the given values into this inequality. If the inequality is true, Yoli’s budget is feasible for a month; if not, then it is not. Thus, by calculating \(30D + F\) and comparing it with \(I\), you determine whether Yoli's budget is feasible.
