i donk know Step-by-step explanation:
First 8.58
Second 8.508
Third 7.5
Fourth 7.058
As the variation is direct we have:

We must find the value of k.
For this, we use the following data:
y = 200 when x = 5
Substituting values we have:

Clearing k:

Then, the function is:

We evaluate the function for x = -3
Answer:
the value of y when x = -3 is:
c.
72
