At the end of a snow storm, Gabriella saw there was a lot of snow on her front lawn. The temperature increased and the snow began to melt at a steady rate. Let S
represent the depth of snow on Gabriella's lawn, in inches, t hours after the snow
stopped falling. The table below has select values showing the linear relationship
between t and S. Determine how many hours it would take for the depth of snow to
reach 7.5 inches.

Given: The snow started melting at a rate of 0.75 inches per hour and it is known that 4 hours after the storm ended, after the storm ended, the depth of snow was down to 9 inches.
Snow melted in 4 hours =
Initial depth of snow = 9 + 3 inches = 12 inches.
Now, depth of snow on Tristan's lawn = Initial depth -0.75(Number of hours)
Let S(t) be the depth of snow on Tristan's lawn, in inches, t hours after the snow stopped falling.
Then,

There are two bc a studen that equals to 2
