Omar helps his mother 1 hour more than his sister does.
x + 1
Step 1 – Choose a variable:
Let the sister help for \(x\) hours.
Step 2 – Use the given relation:
Omar helps 1 hour more than his sister.
Step 3 – Write the expression:
Sister’s time = \(x\)
Extra time Omar helps = \(1\)
So, Omar’s time = \(x\) + \(1\)
Answer: \(x + 1\) hours.
Quick check:
If the sister helps \(2\) hours, then Omar helps \(2 + 1 = 3\) hours. This matches the rule “1 hour more”.
