127

whether it's diameter, or radius, i believe if i remember correctly from school, every amount has to always add up to 180. so if you take 53, and starting adding, long story short, taking 127 and adding it to 53, gives you 180.

okay so, you must add the total of monday amd tuesday

4.32+6.86=11.18

then you subtract the totals from this week and last week

11.18-7.89=3.29

3.29 rounds to 3.30 aka 3.3
