Answer:
Midpoint
Step-by-step explanation:
The midpoint is the point on the segment halfway between the endpoints. It may be the case that the midpoint of a segment can be found simply by counting. If the segment is horizontal or vertical, you can find the midpoint by dividing the length of the segment by 2 and counting that value from either of the endpoints.
This is not middle school work
The answer is 280 because if you multiply 400 by .3 you get 120 and if you subtract 120 from 400 you get 280
