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 Sue's total parking charge would have been $5.00
Jamie parked her car at a garage yesterday, the amount paid was $4.75.
We need to find the number of hours Jamie has parked the car.
Statement 1:
(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.
Total charges = charges for the First hour + $0.75 * ( number of subsequent hours) If the number of hours is N, then the equation becomes
$4.75 = 1 * $1 + (N-1) * $0.75
$ 3.75 = (N-1) * $0.75
(N-1) = $3.75 / $0.75
N-1 = 5
N = 6
Hence,
Sufficient Statement 2:
(2) If the charge for the first hour had been $1.25 Sue's total parking charge would have been $5.00
The charges mentioned is for Sue. We need to find for Jamie.
Hence,
