Question

From Monday to Tuesday, the depth of a snowdrift changed by −238 inches. From Tuesday to Wednesday, the depth changed by half as much. What is the change in the depth of the snowdrift from Tuesday to Wednesday?

Answer 1

-119 inches should be the correct answer. Hope this helps!

Answer 2

The change in the depth of the snowdrift from Tuesday to Wednesday is
`-1(3)/(16)\text{ inches}`.

Explanation:

We are given the following in the question:

Change in snowdrift from Monday to Tuesday =

`-2\displaystyle(3)/(8)\text{ inches}`

Change in snowdrift from Wednesday to Tuesday =

`\displaystyle(1)/(2)\text{ (Change in snowdrift from Monday to Tuesday)}`

Putting the values, we get:

Change in snowdrift from Wednesday to Tuesday =

`=\displaystyle(1)/(2)(-2(3)/(8)) = (1)/(2)* (-19)/(8) = (-19)/(16) = -1(3)/(16)`

Thus, the change in the depth of the snowdrift from Tuesday to Wednesday is
`-1(3)/(16)\text{ inches}`.
