Final Answer:
N = 7.12 + 3.105 = 10.225
O = 2.944 + 1.381 = 4.325
P = 7.938 + 1.343 = 9.281
Q = 0.357 + 0.005 = 0.362
R = 5.97 + 1.62 = 7.59
S = 5.723 + 3.103 = 8.826
T = 4.875 + 2.225 = 7.1
U = 3.651 + 0.015 = 3.666
V = 6.662 + 2.598 = 9.26
W = 8.29 + 9.41 = 17.7
X = 1.63 + 2.07 = 3.7
Y = 4.140 + 1.709 = 5.849
Z = 1.63 + 2.07 = 3.7 (same as X)
A = 8.29 + 9.41 = 17.7 (same as W)
B = 5.97 + 1.62 = 7.59 (same as R)
C = 0.357 + 0.005 = 0.362 (same as Q)
D = 7.12 + 3.105 = 10.225 (same as N)
E = 3.651 + 0.015 = 3.666 (same as U)
F = 2.944 + 1.381 = 4.325 (same as O)
G = 4.875 + 2.225 = 7.1 (same as T)
H = 5.723 + 3.103 = 8.826 (same as S)
I = 7.938 + 1.343 = 9.281 (same as P)
J = 6.662 + 2.598 = 9.26 (same as V)
K = 1.63 + 2.07 = 3.7 (same as X, Z)
L = 4.140 + 1.709 = 5.849 (same as Y)
M = 8.29 + 9.41 = 17.7 (same as W, A)

But the puzzle says: *“The final answer has been done for you.”* — and the box labeled N is filled with 10.225, which matches 7.12 + 3.105.

So the only required final answer (as per the instruction “The final answer has been done for you”) is:

10.225
