Solution

Monthly data left by Peter:
y=2x+50
y=2(21)+50 (substituting x=21 as we have to find data left after 21 days)
y=42+50
y=8
Monthly data left by Peter after 21 days is 8 gigabytes.
Monthly data left by Robert:
From the table, the monthly data left by Robert after 21 days is 14 gigabytes.
The difference between the monthly data left by Robert and Peter after 21 days =148=6 gigabytes.
Option D is correct.
