- Owen parked his car at the carpark at 10.00 a.m. for 1 hour and 28 minutes. How much did he have to pay?
- Natalie parked her car at the car park from 7:20 p.m. on Monday to 11 a.m. on Tuesday. Find the amount of parking fee that she had to pay.
(a)
Amount that Owen had to pay for 1 hour and 28 minutes
= 2.70 + 1.80
= $4.50
(b)
1 h = 60 min
From 7:20 p.m. to 8:20 p.m.:
1 h
Amount that Natalie had to pay from 7:20 p.m. to 8:20 p.m = $2.70
From 8:20 p.m. to 10:00 p.m.: 1 h 40 min
1 h 40 min = 1 x 60 + 40 = 100 min
Number of sets of additional 30 minutes in 1 h 40 min
= 100 ÷ 30
= 3 r 10
Number of sets of additional 30 minutes that Natalie had to pay for
= 3 + 1
= 4
Amount that Natalie had to pay for all the additional 30 minutes or part thereof for 1 h 40 min
= 4 x 1.80
= $7.20
From 10:00 p.m. to 6.30. a.m.
Amount that Natalie had to pay from 10:00 to 6.30 a.m. = $12
From 6.30 a.m. to 11 a.m.: 4 h 30 min
4 h 30 min = 4 x 60 + 30 = 270 min
Number of sets of additional 30 minutes in 4 h 30 min
= 270 ÷ 30
= 9
Amount that Natalie had to pay for all the additional 30 minutes or part thereof for 4 h 30 min
= 9 x 1.80
= $16.20
Total amount that Natalie had to pay
= 2.70 + 7.20 + 12 + 16.20
= $38.10
Answer(s): (a) $4.50; (b) $38.10
