Roshel paid $15.50 for renting a snowboard starting from 15 00. What would be the latest time she must return the snowboard to the shop?
Amount that Roshel paid for all the additional
12 hours
= 15.50 - 3.50
= $12
Number of sets of additional
12 hours
= 12 ÷ 1.50
= 8
Total additional time that Roshel paid for
= 8 x
12= 4 h
Total time that Roshel paid for
= 1 + 4
= 5 h
5 h after 15 00 = 20 00
Latest time that Roshel must return the snowboard to the shop: 20 00
Answer(s): 20 00
