Answer:
The largest possible result she can get is 550
Step-by-step explanation:
Here we have that to find the largest possible result, the numbers from which the last number is subtracted from should be the largest possible, hence
Whereby, we had K × A × N + G × A - R × O × O, then;
K ------- 9
A---------8
N---------7
G---------6
A---------8
R---------2
O---------1
O---------1
will give, 504 + 48 - 2 = 550
If however, the A = 7 and N = 8 we have;
504 + 42 - 2 = 544
Hence, the largest possible result she can get = 550.
