<h3>
Answer: Choice C) 31</h3>
==============================================
Explanation:
The recursive rule
f(n+1)=f(n)-3
can be rearranged to
f(n) = f(n+1)+3
after adding 3 to both sides
----------------
Now let's say we plug in n = 3
f(n) = f(n+1)+3
f(3) = f(3+1)+3
f(3) = f(4)+3
f(3) = 22+3
f(3) = 25
Repeat for n = 2
f(n) = f(n+1)+3
f(2) = f(2+1)+3
f(2) = f(3)+3
f(2) = 25+3
f(2) = 28
Each time we keep adding 3 to get the previous term (since the original recursive rule says to subtract 3 to get the next term; we just go backwards of what the instructions say).
Lastly, we can find that f(1) = f(2)+3 = 28+3 = 31 making the answer to be choice C.

The inequality to find possible <em>distances</em> from Alexandria's home to a park that satisfies the conditions is: 2+D/50≤6 and the distance is 200 miles.
<h3>Inequality</h3>
Minimum distance=(50×2)
Minimum distance=100 miles
Time (T) required to cover the distance (D)
Time=D/50 hours
Inequality is 2+D/50≤6
Hence:
Let solve for Distance (D)
D/55≤6-2
D≤4×50
≤200
Therefore the inequality to find possible <em>distances</em> from Alexandria's home to a park that satisfies the conditions is: 2+D/50≤6 and the distance is 200 miles.
