Final answer:
To budget for utilities with a weekly salary of $635, allocate 10% of the salary, which is approximately $63.50.
Step-by-step explanation:
To determine how much should be budgeted for utilities, you need to consider the percentage of your weekly salary that you are willing to allocate for this expense. Let's assume you want to budget 10% of your weekly salary for utilities.
So, 10% of $635 is (10/100) * $635 = $63.50.
Therefore, the amount you should budget for utilities is approximately $63.50.
