[VJesus12]

Yesterday, Jamie parked her car at a certain parking garage. If Jamie's total parking charge at the garage yesterday was $4.75, for how many hours of parking was she charged?

(1) Parking charges at the garage are $1.00 for the first hour and $0.75 for each additional hour or fraction of the hour.
(2) If the charge for the first hour had been $1.25 Jamie's total parking charge would have been $5.00

OA is A.

I don't know how could I use statement (2) and conclude it is not sufficient. Experts, I would appreciate your help.

S2 tells us that the first hour cost $1.25, then that leaves $3.75 for the remaining hours.

This could mean, the second hour cost $3.75 or the next 3 hours cost $1.25 each. This does not tell us exactly how many hours the car was parked. So, INSUFFICIENT.
