- Dylan parked his car at the carpark at 6.00 p.m. for 1 hour and 40 minutes. How much did he have to pay?
- Anna parked her car at the car park from 6:20 p.m. on Monday to 10 a.m. on Tuesday. Find the amount of parking fee that she had to pay.
(a)
Amount that Dylan had to pay for 1 hour and 40 minutes
= 2.90 + 2.20 + 2.20
= $7.30
(b)
1 h = 60 min
From 6:20 p.m. to 7:20 p.m.:
1 h
Amount that Anna had to pay from 6:20 p.m. to 7:20 p.m = $2.90
From 7:20 p.m. to 10:00 p.m.: 2 h 40 min
2 h 40 min = 2 x 60 + 40 = 160 min
Number of sets of additional 30 minutes in 2 h 40 min
= 160 ÷ 30
= 5 r 10
Number of sets of additional 30 minutes that Anna had to pay for
= 5 + 1
= 6
Amount that Anna had to pay for all the additional 30 minutes or part thereof for 2 h 40 min
= 6 x 2.20
= $13.20
From 10:00 p.m. to 6.30. a.m.
Amount that Anna 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 Anna had to pay for all the additional 30 minutes or part thereof for 3 h 30 min
= 7 x 2.20
= $15.40
Total amount that Anna had to pay
= 2.90 + 13.20 + 12 + 15.40
= $43.50
Answer(s): (a) $7.30; (b) $43.50
