Answer
To represent Ciarán's usage, add 2 GB to all of Frank's data points in the graph:
Week 1: 3 GB (Frank) → 5 GB (Ciarán)
Week 2: 2 GB (Frank) → 4 GB (Ciarán)
Week 3: 5 GB (Frank) → 7 GB (Ciarán)
Week 4: 3 GB (Frank) → 5 GB (Ciarán)
Week 5: 2 GB (Frank) → 4 GB (Ciarán)
Plot these new values on the graph with Ciarán's line above Frank's.
