Final answer:
To find Roxy's average monthly expense for her dog and food, as well as the budgeted amount for household and personal supplies, we need the actual figures from the student's problem. Without this information, it is not possible to provide accurate answers.
Step-by-step explanation:
To find Roxy's average monthly expense for her dog, we need to round the figure to the nearest whole dollar. We need more information to calculate this, as the question only provides us with a blank space. Similarly, we need more information to calculate the average amount Roxy spends on food each month. Lastly, we are also missing the month in which Roxy spent more on household and personal supplies. However, we know that she plans to budget the average amount for this expense, which is also not provided.
Without the missing figures, it is not possible to provide accurate answers. To calculate the average monthly expense for the dog and food, we need the actual figures from the student's problem. Additionally, we need the month in question for the household and personal supplies expense.
