Answer: extrapolation, and 25 months
Step-by-step explanation:
I took the Plato test and got it right, but if you want to know. Interpolation means based on the numbers given you could see the answer, extrapolation means you have to go farther than the last plot point given to get your answer. Which you do since it does not go past 12 months.
The second answer you can roughly get by pluging in each of the choices in the equation for x
For example: y=-200.22(25)+5015.20
That should give you an answer pretty close to zero so there is your answer
