A man has an average expenditure of $200 per month. If he spends $250 in the first month, what will be his average expenditure for the first two months?
Step 1: Identify the man's average expenditure per month, which is $200.
Step 2: Note that in the first month, he spends $250.
Step 3: Calculate the total expenditure for the first two months by adding the first month's expenditure ($250) to the average expenditure for the second month ($200).
Step 4: Total expenditure = 250 + 200 = 450.
Step 5: To find the average expenditure for the two months, divide the total expenditure (450) by the number of months (2).
Step 6: Average expenditure = 450 / 2 = 225.
