Since the skier has to rent skis for 30 dollars per day with
both passes, we can ignore it while solving the question.
A season pass is 350, while a daily pass is 75.

So a seasonal pass is equivalent to having 4.6667 daily passes. And you can't buy 0.6667 of a pass.
So, if you went at least 5 days with a seasonal pass, then the seasonal pass would be less expensive than a daily pass.
Answer:
A. 15,840 feet
Step-by-step explanation:
1 mile = 5,280 feet (I think "five tomatoes" is helpful: five tomatoes --> five-two-eight-oh)
multiply both sides of equation by 3: 1 * 3 = 5,280 * 3
simplify: 3 miles = 15,840 feet, which means A is the answer
