On the design plan for a garden, a straight path suns from (25,20) to (40,36). A lamp is going to be placed at the midpoint of the path. Determine the coordinates for the lamp.

midpoint: (25+20)/2, (20+36)/2

To find the coordinates of the lamp, you have the find the midpoint of the path.
The path has two endings:
one at (25, 20)
one at (40, 36)
For the xcoordinate, add up all xcoordinates and divide them by 2
 [(25 + 40) / 2] = (15 / 2) = 7.5
For the ycoordinate, add up all ycoordinates and divide them b y 2
 [(20 + 36) / 2] = (56 / 2) = 28
So the coordinates of the lamp will be
(7.5, 28)
Because it is in the midpoint of the path (midpoint of both ends)
