Every additional 12 hour |
$3.50 |
Min paid $18 for renting a snowboard starting from 14 00. What would be the latest time she must return the snowboard to the shop?
Amount that Min paid for all the additional
12 hours
= 18 - 7.50
= $10.50
Number of sets of additional
12 hours
= 10.50 ÷ 3.50
= 3
Total additional time that Min paid for
= 3 x
12= 1
12 h
Total time that Min paid for
= 1 + 1
12= 2

12 h after 14 00 = 16 30
Latest time that Min must return the snowboard to the shop: 16 30
