How much money should I ask my parents for?

Ok today was our last day of school, but I asked if I could go shopping this weekend since theres only 3 t-shirts that I usually wear and 2 good pairs of shorts and I need much more for this summer. I want to go to Hollister and heres the problem about that: The nearest store is located 10 miles away, and idk if my parents wanna take me that far. There is also a bus system that takes us there. but anyways about the money, I was thinking $100 but I think that will be too much money but i also need it. I plan on running into the store and heading to the clearance section where i could buy 2 t-shirts and 3 pairs of shorts. One t-shirt i want is $10.43, the other one is $11.18. I also wanna get 3 pairs of the sweatpant shorts in different colors witch is $59.40. The tax in this area is 6% and i found the total to be $ 82.31, witch i think is smart shopping. also how do i remember what my clothes i want look like?
