Answer:
D -9
Step-by-step explanation:
(g o f)(-1) = g(f(-1))
f(-1) = 
g(-4) = -4 - 5 = -9
So, (g o f)(-1) = -9
Starting equation:
92=J+L+B
To find how much money Jane has, we use the equation:
J=5+3L
To find how much money Bob has, we use the equation:
B=4L-1
Enter those equations in the problem
92=(5+3L)+L+(4L-1)
Combine like terms
92=4+8L
Subtract 4 to isolate variable
88=8L
Divide by 8 to isolate variable
11=L
Answer:
Lonnie has $11
Jane has $38
Bob has $43
side note: Lonnie is that one poor friend we all have
