Blababa [14]

Answer:

8.5 inches

Step-by-step explanation:

First let's find the time t when the depth of the snow is 7 inches.

To do this, we just need to use the value of D = 7 then find the value of t:

$7 = 1.5t + 4$

$1.5t = 3$

$t = 2\ hours$

We want to find the depth of snow one hour from now, so we just need to use the value of t = 3 to calculate D:

$D = 1.5*3 + 4$

$D = 4.5 + 4 = 8.5\ inches$

The depth of snow one hour from now will be 8.5 inches.
