Step-by-step explanation:
Hi again Lacy!
The answer would be 45.3. The same steps I took with the last question applies here, just this time in the TENTHS instead of HUNDREDTHS (I almost didn't catch that myself until I reread the problem and Kmc's post xP)
45.3297 -> 45.330 -> 45.33 -> 45.3
2463.73 - 183.70 + 678.57 - 35.06 = 3142.30 - 218.76 = 2923.54 (new balance)
I think you spelled that word wrong but it is a 19 sided polygon
