Answer:

After 3 hours: 4 inches

After t hours: 13  - 3t

Step-by-step explanation:

Initial height of snow = 13 inches.

Rate of melting snow = 3 in./hour

Let h = height of snow, and t = time in hours.

The equation that represents the height of the snow after t hours is:

h = 13 - 3t

After 3 hours:

t = 3

h = 13 - 3(3) = 13 - 9 = 4

After t hours:

h = 13  - 3t
