Let's start by setting up an equation to represent the total cost of the rental:

Total Cost = $35 (daily fee) + $0.25 (cost per mile) * Number of Miles Driven

We want to find the maximum number of miles Denise can drive while keeping the total cost at or below $55. So we can set up an inequality:

35 + 0.25x ≤ 55

Subtracting 35 from both sides gives:

0.25x ≤ 20

Dividing both sides by 0.25 gives:

x ≤ 80

So the maximum number of miles Denise can drive while staying within her budget is 80 miles. Therefore, the answer is B. 80 miles.
