Can someone help me on this? I know the answer is 5 more pages, but I need an actual mathematical explanation. Brainliest and points!!

Answer:
5
Step-by-step explanation:
Add up the pages Javi read (10 + 20 + 60 + 20 + 15) = 125
Add up the pages MeriAnne read (20 + 30 + 40 +20 + 10) = 120
125 - 120 = 5
Javi is the winner and read 5 more pages than MeriAnne.
