Answer:
Friday & Sunday
Step-by-step explanation:
Thursday: 287
Friday: 618
Saturday: 973
Sunday: 532
973 < 287 + 618 = 973 < 905
We now know this isn't true.
973 < 287 + 532 = 973 < 819
This isn't true either.
973 < 532 + 618 = 973 < 1150
This is true. The two days with the time are Friday and Sunday.
I really hope this helps you! Tell me if it's right or not! :D
