Answer:
On the graph, the point balances for the three friends on the 23rd week are:
- Friend A: 60 points
- Friend B: 80 points
- Friend C: 40 points
On the 24th week, the point balances are:
- Friend A: 80 points
- Friend B: 100 points
- Friend C: 60 points
It looks like all three friends are earning points and increasing their balances over time. Friend B seems to be earning points at a faster rate than the other two friends, as their balance is consistently higher. Friend C has the lowest balance, but is still earning points and increasing their balance.
