Perry parked his car at the carpark from 2.39 p.m to 5 p.m. How much did he pay for his parking?
From 2.39 p.m. to 3.39 p.m.: 1 h
From 3.39 p.m. to 5 p.m.: 1 h 21 min
1 h = 60 min
1 h 21 min = 1 x 60 + 21 = 81 min
Number of sets of addtional 30 min in 2 h 21 min
= 81 ÷ 30
= 2 r 21
Number of sets of 30 min that Perry had to pay for
= 2 + 1
= 3
Amount that Perry had to pay for 3 sets of additional 30 min
= 3 x 1.70
= $5.10
Total amount that Perry had to pay for his parking
= 2.30 + 5.10
= $7.40
Answer(s): $7.40
