Final answer:
John spends $600, which is 40% of his total monthly spending, on one category of his budget. However, without more context, we cannot specify if it is for rent, savings, entertainment, or food.
Step-by-step explanation:
To determine what 40% of John's total monthly spending of $1500 goes to, you can calculate the amount by using a simple percentage formula. In this case, 40% of $1500 is calculated as 0.40 × $1500, which equals $600. So, John spends $600 of his monthly budget on a single category, but the question does not specify which category it is. It could be rent, savings, entertainment, or food.
To provide an exact answer, we would need additional information that indicates the specific category related to the 40% spending.
When dealing with personal finances, creating a budget and understanding expenses are crucial steps. This involves not just fixed costs such as rent or mortgage payments, but also variable costs like groceries, utilities, and entertainment.
