- Fred parked his car at the carpark at 7.00 p.m. for 1 hour and 52 minutes. How much did he have to pay?
- Joelle parked her car at the car park from 1:10 p.m. on Monday to 11 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 52 minutes
= 2.70 + 2.20 + 2.20
= $7.10
(b)
1 h = 60 min
From 1:10 p.m. to 2:10 p.m.:
1 h
Amount that Joelle had to pay from 1:10 p.m. to 2:10 p.m = $2.70
From 2:10 p.m. to 10:00 p.m.: 7 h 50 min
7 h 50 min = 7 x 60 + 50 = 470 min
Number of sets of additional 30 minutes in 7 h 50 min
= 470 ÷ 30
= 15 r 20
Number of sets of additional 30 minutes that Joelle had to pay for
= 15 + 1
= 16
Amount that Joelle had to pay for all the additional 30 minutes or part thereof for 7 h 50 min
= 16 x 2.20
= $35.20
From 10:00 p.m. to 6.30. a.m.
Amount that Joelle 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 Joelle had to pay for all the additional 30 minutes or part thereof for 4 h 30 min
= 9 x 2.20
= $19.80
Total amount that Joelle had to pay
= 2.70 + 35.20 + 12 + 19.80
= $69.70
Answer(s): (a) $7.10; (b) $69.70
