Answer:
Effect = $5500
Explanation:
Given data:
Service amount =$3000
Received cash amount $8000
Expenses for repair = $900
Paid to supplier = $1600
Received cash amount is $8000
Paid cash = $1600 + $900
Paid cash= $2500
combined effect is calculated as
combined effect = received cash - paid cash
Effect = $8000 - $2500
Effect = $5500
