- Jack parked his car at the carpark at 8.00 p.m. for 1 hour and 21 minutes. How much did he have to pay?
- Opal parked her car at the car park from 4:50 p.m. on Monday to 10 a.m. on Tuesday. Find the amount of parking fee that she had to pay.
(a)
Amount that Jack had to pay for 1 hour and 21 minutes
= 2.10 + 1.30
= $3.40
(b)
1 h = 60 min
From 4:50 p.m. to 5:50 p.m.:
1 h
Amount that Opal had to pay from 4:50 p.m. to 5:50 p.m = $2.10
From 5:50 p.m. to 10:00 p.m.: 4 h 10 min
4 h 10 min = 4 x 60 + 10 = 250 min
Number of sets of additional 30 minutes in 4 h 10 min
= 250 ÷ 30
= 8 r 10
Number of sets of additional 30 minutes that Opal had to pay for
= 8 + 1
= 9
Amount that Opal had to pay for all the additional 30 minutes or part thereof for 4 h 10 min
= 9 x 1.30
= $11.70
From 10:00 p.m. to 6.30. a.m.
Amount that Opal had to pay from 10:00 to 6.30 a.m. = $7
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 Opal had to pay for all the additional 30 minutes or part thereof for 3 h 30 min
= 7 x 1.30
= $9.10
Total amount that Opal had to pay
= 2.10 + 11.70 + 7 + 9.10
= $29.90
Answer(s): (a) $3.40; (b) $29.90
