The compound inequality to describe the elevation of Ted's house is 135 > x > 128.

Ted lives between 128m and 135m above sea level.

Now it is given that,

Sakura's house is at an elevation between 113 m and 120 m above sea level.

Let x be the elevation of Sakura's house.

So, 120 > x > 113

Now Ted lives about 15 m below her

Ted's house elevation = x - 15

So, the compound inequality to describe the elevation of Ted's house,

120 > x - 15 > 113

Adding 15 to the inequality we get,

120 + 15 > x - 15 + 15 > 113 + 15

Solving we get,

135 > x > 128

This is the required compound inequality.

Thus, the compound inequality to describe the elevation of Ted's house is 135 > x > 128.
