Answer:
125
Step-by-step explanation: 8000 divided by 2 is 4000. So they paid 4000 in the first month. You do that same equation 6 times dividing the remainder by 2 each time.
The notation just means
(f/g)(-4) = f(-4) / g(-4)
If f(x) = x² + 2 and g(x) = 1 - 3x, then
f(-4) = (-4)² + 2 = 16 + 2 = 18
g(-4) = 1 - 3 (-4) = 1 + 12 = 13
and so
(f/g)(-4) = 18/13
