First, we need to simplify the expression inside the parentheses: 9-3 = 6.
Next, we substitute 6 in for n in the function K(n):
K(6) = 120 + 55(6)
K(6) = 120 + 330
K(6) = 450
Therefore, the value of K(9-3) is $450. Answer: $\boxed{450}$.
Next, we substitute 6 in for n in the function K(n):
K(6) = 120 + 55(6)
K(6) = 120 + 330
K(6) = 450
Therefore, the value of K(9-3) is $450. Answer: $\boxed{450}$.
