Final answer:
John spends $1275 on things other than heating, electricity, and utilities.
Step-by-step explanation:
To find out how much John spends on things other than heating, electricity, and utilities, we need to first calculate the amount he spends on heating and electricity. We know that 15% of his spendings on utilities goes towards heating and electricity. So, we can calculate this by finding 15% of his total monthly spending.
15% of $1500 = $225
Now, we can find out how much John spends on things other than heating, electricity, and utilities by subtracting the amount he spends on heating and electricity from his total monthly spending.
Total spending - Spending on heating and electricity = Spending on things other than heating, electricity, and utilities
$1500 - $225 = $1275
Therefore, John spends $1275 on things other than heating, electricity, and utilities.
