Question

On Monday, the lake's water level was 38 inches deep. On Tuesday, the water level changed 6 inches. Using integers, explain two ways that the water level could have changed.

Answer 1

44 inches

32 inches

Explanation:

Given that :

Depth of water level on Monday = 38 inches deep

Change in depth of water level on Tuesday = 6 inches

Two ways water level could have changed :

Water level could have ehave risen by 6 inches on Tuesday to give a depth of:

Initial depth + change in depth = (38 + 6) inches = 44 inches

Or

Water level could have fallen by 6 inches on Tuesday to give a depth of :

(initial depth + depth change) = (38 - 6) inches = 32 inches
