- Zane parked his car at the carpark at 12.00 p.m. for 1 hour and 19 minutes. How much did he have to pay?
- Zoe parked her car at the car park from 6:15 p.m. on Monday to 9 a.m. on Tuesday. Find the amount of parking fee that she had to pay.
(a)
Amount that Zane had to pay for 1 hour and 19 minutes
= 2.90 + 2.30
= $5.20
(b)
1 h = 60 min
From 6:15 p.m. to 7:15 p.m.:
1 h
Amount that Zoe had to pay from 6:15 p.m. to 7:15 p.m = $2.90
From 7:15 p.m. to 10:00 p.m.: 2 h 45 min
2 h 45 min = 2 x 60 + 45 = 165 min
Number of sets of additional 30 minutes in 2 h 45 min
= 165 ÷ 30
= 5 r 15
Number of sets of additional 30 minutes that Zoe had to pay for
= 5 + 1
= 6
Amount that Zoe had to pay for all the additional 30 minutes or part thereof for 2 h 45 min
= 6 x 2.30
= $13.80
From 10:00 p.m. to 6.30. a.m.
Amount that Zoe had to pay from 10:00 to 6.30 a.m. = $12
From 6.30 a.m. to 9 a.m.: 2 h 30 min
2 h 30 min = 2 x 60 + 30 = 150 min
Number of sets of additional 30 minutes in 2 h 30 min
= 150 ÷ 30
= 5
Amount that Zoe had to pay for all the additional 30 minutes or part thereof for 2 h 30 min
= 5 x 2.30
= $11.50
Total amount that Zoe had to pay
= 2.90 + 13.80 + 12 + 11.50
= $40.20
Answer(s): (a) $5.20; (b) $40.20
