Charlie parked his car at the carpark from 6.48 p.m to 9 p.m. How much did he pay for his parking?
From 6.48 p.m. to 7.48 p.m.: 1 h
From 7.48 p.m. to 9 p.m.: 1 h 12 min
1 h = 60 min
1 h 12 min = 1 x 60 + 12 = 72 min
Number of sets of addtional 30 min in 2 h 12 min
= 72 ÷ 30
= 2 r 12
Number of sets of 30 min that Charlie had to pay for
= 2 + 1
= 3
Amount that Charlie had to pay for 3 sets of additional 30 min
= 3 x 1.80
= $5.40
Total amount that Charlie had to pay for his parking
= 2.70 + 5.40
= $8.10
Answer(s): $8.10
