This past February, Ms. Wilson asked her class to keep track of the temperature every day for one week. They made a chart to post the outdoor temperatures for each day of the school week at 9:00 a.m. and at noon.

1. On Monday, the temperature was 31 degrees Fahrenheit at noon. It had been 10 degrees colder that morning at 9:00 a.m.
2. Thursday's 9:00 a.m. temperature was double the temperature for the same time on Monday.
3. On Wednesday and Thursday, the temperature rose 6 degrees from nine o'clock until noon.
4. Tuesday morning at 9:00 a.m., the temperature was 10 degrees warmer than on Monday at the same time. At noon on Tuesday, it was exactly at the freezing mark.
5. Wednesday noon was 3 degrees colder than Thursday noon.
6. The first reading on Friday was 5 degrees colder than the day before at the same time. It warmed up 5 degrees each hour until noon.

What was the temperature each day at 9:00 a.m. and at noon?

Read your structured  solution and found that it supports my reservations   regarding puzzle's quality.

Your solution is (and rightly so) a repeated application of a

not-so-complicated formula a+b=c, no creativity required.

IMHO the level of  "filtering" at the review board should be taken

a little bit more  seriously.
