- Fred parked his car at the carpark at 8.00 a.m. for 1 hour and 25 minutes. How much did he have to pay?
- Julie parked her car at the car park from 2:35 p.m. on Monday to 10 a.m. on Tuesday. Find the amount of parking fee that she had to pay.
(a)
Amount that Fred had to pay for 1 hour and 25 minutes
= 2.40 + 1.50
= $3.90
(b)
1 h = 60 min
From 2:35 p.m. to 3:35 p.m.:
1 h
Amount that Julie had to pay from 2:35 p.m. to 3:35 p.m = $2.40
From 3:35 p.m. to 10:00 p.m.: 6 h 25 min
6 h 25 min = 6 x 60 + 25 = 385 min
Number of sets of additional 30 minutes in 6 h 25 min
= 385 ÷ 30
= 12 r 25
Number of sets of additional 30 minutes that Julie had to pay for
= 12 + 1
= 13
Amount that Julie had to pay for all the additional 30 minutes or part thereof for 6 h 25 min
= 13 x 1.50
= $19.50
From 10:00 p.m. to 6.30. a.m.
Amount that Julie had to pay from 10:00 to 6.30 a.m. = $12
From 6.30 a.m. to 10 a.m.: 3 h 30 min
3 h 30 min = 3 x 60 + 30 = 210 min
Number of sets of additional 30 minutes in 3 h 30 min
= 210 ÷ 30
= 7
Amount that Julie had to pay for all the additional 30 minutes or part thereof for 3 h 30 min
= 7 x 1.50
= $10.50
Total amount that Julie had to pay
= 2.40 + 19.50 + 12 + 10.50
= $44.40
Answer(s): (a) $3.90; (b) $44.40
