Okay, your function rule is:
[tex]\sf y=x+13[/tex]
Where 'x' is number of hours and 'y' is the depth of the snow on the ground.
There are 10 hours between noon and 10 P.M., so let's plug this in for 'x' in the function:
[tex]\sf y=10+13[/tex]
Add:
[tex]\sf y=\boxed{\sf 23~in}[/tex]
So the snow will be 23 inches deep when the news airs at 10 P.M.
