Answer:
B. $1.45 + $0.55x ≤ $35; x ≤ 61 miles
Step-by-step explanation:
The mileage charge for x miles will be $0.55x, so the total charge will be $1.45+$0.55x. This must be less than or equal to $35 for Ariel to be able to pay for her travel. The appropriate inequality is ...
$1.45 +$0.55x ≤ $35 . . . . . matches choice B

<em>Comment on selecting an answer</em>
From a "reasonableness" point of view, any answer choice with "≥ $35" can be eliminated immediately. Further, any answer choice with $1.45x can be eliminated, since the mileage charge is not $1.45, it is $0.55. The leaves only the choice shown above.
