Your answer is D because $25 is a fixed one-time cost, and then you pay $4 every time you visit (x is the amount of times you visit). Your monthly total is $53, and 25 + 4x = 53 sums it up exactly.
This looks kinda difficult ngl I’ll see if I can do it:)
It's C they are just out of order for the years.
f(x)=35.5x+6
For each year your plug in the snow total for x and solve
2006 x=53 so 35.5(53)+6=1887.5
2007 x=42 so 35.5(42)+6=1497
2008 x=55 so 35.5(55)+6=1958.5
2009 x=63 so 35.5(63)+6=2242.5
2010 x=58 so 35.5(58)+6=2065
2011 x=47 so 35.5(47)+6=1674.5
Hope that helps.
