Oscar parked his car at the carpark from 6.37 p.m to 10 p.m. How much did he pay for his parking?
From 6.37 p.m. to 7.37 p.m.: 1 h
From 7.37 p.m. to 10 p.m.: 2 h 23 min
1 h = 60 min
2 h 23 min = 2 x 60 + 23 = 143 min
Number of sets of addtional 30 min in 3 h 23 min
= 143 ÷ 30
= 4 r 23
Number of sets of 30 min that Oscar had to pay for
= 4 + 1
= 5
Amount that Oscar had to pay for 5 sets of additional 30 min
= 5 x 1.30
= $6.50
Total amount that Oscar had to pay for his parking
= 2.10 + 6.50
= $8.60
Answer(s): $8.60
