The table shows how much a shop charges a customer for renting a bicycle.
Time |
Charges |
First hour |
$7.50 |
Every additional 12 hour |
$3.50 |
Min paid $35.50 for renting a bicycle starting from 16 00. What would be the latest time she must return the bicycle to the shop?
Amount that Min paid for all the additional
12 hours
= 35.50 - 7.50
= $28
Number of sets of additional
12 hours
= 28 ÷ 3.50
= 8
Total additional time that Min paid for
= 8 x
12= 4 h
Total time that Min paid for
= 1 + 4
= 5 h
5 h after 16 00 = 21 00
Latest time that Min must return the bicycle to the shop: 21 00
Answer(s): 21 00
