2500
3000
3500
4000
Total income of 4 members = 4 * 3000 = 12000. Income of other 3 members = 12000 - 4000 = 8000. Average = 8000 / 3 = 2666.67, approximately 2500.

Q
Q: A family has 4 members with an average income of $3000. If the father earns $4000, what is the average income of the other three members?
Solution: Total income of 4 members = 4 * 3000 = 12000. Income of other 3 members = 12000 - 4000 = 8000. Average = 8000 / 3 = 2666.67, approximately 2500.
Steps: 4
Step 1: Calculate the total income of the 4 family members by multiplying the average income by the number of members. Total income = 4 members * $3000 = $12000.
Step 2: Subtract the father's income from the total income to find the income of the other 3 members. Income of other 3 members = $12000 - $4000 = $8000.
Step 3: Calculate the average income of the other 3 members by dividing their total income by 3. Average income = $8000 / 3 = $2666.67.
Step 4: Round the average income to the nearest hundred for simplicity. The average income is approximately $2500.
