Luke parked his car at the carpark from 3.53 p.m to 9 p.m. How much did he pay for his parking?
From 3.53 p.m. to 4.53 p.m.: 1 h
From 4.53 p.m. to 9 p.m.: 4 h 7 min
1 h = 60 min
4 h 7 min = 4 x 60 + 7 = 247 min
Number of sets of addtional 30 min in 5 h 7 min
= 247 ÷ 30
= 8 r 7
Number of sets of 30 min that Luke had to pay for
= 8 + 1
= 9
Amount that Luke had to pay for 9 sets of additional 30 min
= 9 x 1.90
= $17.10
Total amount that Luke had to pay for his parking
= 2.40 + 17.10
= $19.50
Answer(s): $19.50
