Nora paid $36.50 for renting a snowboard starting from 12 00. What would be the latest time she must return the snowboard to the shop?
Amount that Nora paid for all the additional
12 hours
= 36.50 - 8.50
= $28
Number of sets of additional
12 hours
= 28 ÷ 3.50
= 8
Total additional time that Nora paid for
= 8 x
12= 4 h
Total time that Nora paid for
= 1 + 4
= 5 h
5 h after 12 00 = 17 00
Latest time that Nora must return the snowboard to the shop: 17 00
Answer(s): 17 00
